Abstract = {A two-dimensional, anisotropic superconductivity was
recently found at the KTaO<sub>3</sub>(111) interfaces. The
nature of the anisotropic superconducting transition remains
a subject of debate. To investigate the origins of the
observed behavior, we grew epitaxial KTaO<sub>3</sub>(111)-based
heterostructures. We show that the superconductivity is
robust against the in-plane magnetic field and violates the
Pauli limit. We also show that the Cooper pairs are more
resilient when the bias is along [11[Formula: see text]] (I
∥ [11[Formula: see text]]) and the magnetic field is along
[1[Formula: see text]0] (<i>B</i> ∥ [1[Formula: see
text]0]). We discuss the anisotropic nature of
superconductivity in the context of electronic structure,
orbital character, and spin texture at the
KTaO<sub>3</sub>(111) interfaces. The results point to
future opportunities to enhance superconducting transition
temperatures and critical fields in crystalline,
two-dimensional superconductors with strong spin-orbit
coupling.},

Abstract = {We investigate supercurrent interference patterns measured
as a function of magnetic field in ballistic graphene
Josephson junctions. At high doping, the expected
φ0-periodic "Fraunhofer"pattern is observed, indicating a
uniform current distribution. Close to the Dirac point, we
find anomalous interferences that are close to a 2φ0
periodicity, similar to that predicted for topological
Andreev bound states carrying a charge of e instead of 2e.
This feature persists with increasing temperature, ruling
out a nonsinusoidal current-phase relationship. It also
persists in junctions in which sharp vacuum edges are
eliminated. Our results indicate that the observed behavior
may originate from an intrinsic property of ballistic
graphene Josephson junctions, though the exact mechanism
remains unclear.},

Abstract = {We investigate the critical current I_{C} of ballistic
Josephson junctions made of encapsulated
graphene-boron-nitride heterostructures. We observe a
crossover from the short to the long junction regimes as the
length of the device increases. In long ballistic junctions,
I_{C} is found to scale as ∝exp(-k_{B}T/δE). The
extracted energies δE are independent of the carrier
density and proportional to the level spacing of the
ballistic cavity. As T→0 the critical current of a long
(or short) junction saturates at a level determined by the
product of δE (or Δ) and the number of the junction's
transversal modes.},

the oscillations within a four-level model of the

in high magnetic fields normal to the quantum wells layers
show that both the oscillations frequency and phase depend

contacts shaped to form a narrow constriction, less than

superconducting contacts and able to withstand magnetic
fields high enough to reach the quantum Hall regime in
graphene. In this regime, the device conductance is
determined by edge states, plus the contribution from the
constricted region. In particular, the constriction area can
support supercurrents up to fields of ∼2.5T. Additionally,
enhanced conductance is observed through a wide range of
magnetic fields and gate voltages. This additional
conductance and the appearance of supercurrent is attributed
to the tunneling between counterpropagating quantum Hall
edge states along opposite superconducting
contacts.},

Abstract = {We present transport measurements on long, diffusive,
graphene-based Josephson junctions. Several junctions are
made on a single-domain crystal of CVD graphene and feature
the same contact width of ∼9 μm but vary in length from
400 to 1000 nm. As the carrier density is tuned with the
gate voltage, the critical current in these junctions ranges
from a few nanoamperes up to more than 5 μA, while the
Thouless energy, ETh, covers almost 2 orders of magnitude.
Over much of this range, the product of the critical current
and the normal resistance ICRN is found to scale linearly
with ETh, as expected from theory. However, the value of the
ratio ICRN/ETh is found to be 0.1-0.2, which much smaller
than the predicted ∼10 for long diffusive SNS
junctions.},

Abstract = {The dynamical properties of multiterminal Josephson
junctions (MT-JJs) have attracted interest, driven by the
promise of new insights into synthetic topological phases of
matter and Floquet states. This effort has culminated in the
discovery of Cooper multiplets in which the splitting of a
Cooper pair is enabled via a series of Andreev reflections
that entangle four (or more) electrons. Here, we show that
multiplet resonances can also emerge as a consequence of the
three-terminal circuit model. The supercurrent appears due
to correlated phase dynamics at values that correspond to
the multiplet condition <i>nV</i><sub>1</sub> =
-<i>mV</i><sub>2</sub> of applied bias. Multiplet resonances
are seen in nanofabricated three-terminal graphene JJs,
analog three-terminal JJ circuits, and circuit simulations.
The stabilization of the supercurrent is purely dynamical,
and a close analog to Kapitza's inverted pendulum problem.
We describe parameter considerations that optimize the
detection of the multiplet lines both for design of future
devices.},

Abstract = {We study the evolution of conductance regimes in carbon
nanotubes with doubly degenerate orbitals (shells) by

For sufficiently open contacts, Kondo behavior is observed
for 1, 2, and 3 electrons in the topmost shell. As the
contacts are opened more, the sample enters the "mixed
valence" regime, where different charge states are strongly
hybridized by electron tunneling. Here, the conductance as a
function of gate voltage shows pronounced modulations with a
period of four electrons, and all single-electron features
are washed away at low temperature. We successfully describe
this behavior by a simple formula with no fitting
parameters. Finally, we find a surprisingly small energy
scale that controls the temperature evolution of conductance
and the tunneling density of states in the mixed valence
regime.},

Abstract = {Time‐resolved four‐wave mixing is used to study electron
scattering in modulation‐doped GaAs quantum wells in high
magnetic fields up to 8T. A strong increase in dephasing
times in strong magnetic fields is observed and attributed
to a decrease in the scattering rates relative to zero
field. An early time signal in high magnetic field is found,
which is due to a polarization interaction process. A strong
enhancement of the signal at the absorption edge is measured
which is attributed to the Fermi edge singularity. Copyright

Abstract = {The vanishing band gap of graphene has long presented
challenges for making high-quality quantum point contacts
(QPCs)─the partially transparent p-n interfaces introduced
by conventional split gates tend to short circuit the QPCs.
This complication has hindered the fabrication of graphene
quantum Hall Fabry-Pérot interferometers, until recent
advances have allowed split-gate QPCs to operate utilizing
the highly resistive ν = 0 state. Here, we present a simple
recipe to fabricate QPCs by etching a narrow trench in the
graphene sheet to separate the conducting channel from
self-aligned graphene side gates. We demonstrate operation
of the individual QPCs in the quantum Hall regime and
further utilize these QPCs to create and study a quantum
Hall interferometer.},

Abstract = {The coexistence of semiconducting and metallic single-walled
carbon nanotubes (SWNTs) during synthesis is one of the
major bottlenecks that prevent their broad application for
the next-generation nanoelectronics. Herein, we present more
understanding and demonstration of the growth of highly
enriched semiconducting SWNTs (s-SWNTs) with a narrow
diameter distribution. An important fact discovered in our
experiments is that the selective elimination of metallic
SWNTs (m-SWNTs) from the mixed arrays grown on quartz is
diameter-dependent. Our method emphasizes controlling the
diameter distribution of SWNTs in a narrow range where
m-SWNTs can be effectively and selectively etched during
growth. In order to achieve narrow diameter distribution,
uniform and stable Fe-W nanoclusters were used as the
catalyst precursors. About 90% of as-prepared SWNTs fall
into the diameter range 2.0-3.2 nm. Electrical measurement
results on individual SWNTs confirm that the selectivity of
s-SWNTs is ∼95%. The present study provides an effective
strategy for increasing the purity of s-SWNTs via
controlling the diameter distribution of SWNTs and adjusting
the etchant concentration. Furthermore, by carefully
comparing the chirality distributions of Fe-W-catalyzed and
Fe-catalyzed SWNTs under different water vapor
concentrations, the relationship between the
diameter-dependent and electronic-type-dependent etching
mechanisms was investigated.},

interface in the direction determined by the magnetic field
and their interference can turn an incoming electron into an
out- going electron or hole, depending on the phase
accumulated by the CAESs along their path. Our results
demonstrate that these excitations can propagate and

Abstract = {The computational complexity of the brain depends in part on
a neuron's capacity to integrate electrochemical information
from vast numbers of synaptic inputs. The measurements of
synaptic activity that are crucial for mechanistic
understanding of brain function are also challenging,
because they require intracellular recording methods to
detect and resolve millivolt- scale synaptic potentials.
Although glass electrodes are widely used for intracellular
recordings, novel electrodes with superior mechanical and
electrical properties are desirable, because they could
extend intracellular recording methods to challenging
environments, including long term recordings in freely
behaving animals. Carbon nanotubes (CNTs) can theoretically
deliver this advance, but the difficulty of assembling CNTs
has limited their application to a coating layer or assembly
on a planar substrate, resulting in electrodes that are more
suitable for in vivo extracellular recording or
extracellular recording from isolated cells. Here we show
that a novel, yet remarkably simple, millimeter-long
electrode with a sub-micron tip, fabricated from
self-entangled pure CNTs can be used to obtain intracellular
and extracellular recordings from vertebrate neurons in
vitro and in vivo. This fabrication technology provides a
new method for assembling intracellular electrodes from
CNTs, affording a promising opportunity to harness
nanotechnology for neuroscience applications.},

done in order to distinguish two potential mechanisms: (a)
supercurrents independently flowing along both non-contacted

more superconducting contacts, coupling between different
pairs of terminals must be taken into account and the state
of the junction evolves in a phase space of higher
dimensionality. Here, we study the multiterminal inverse AC
Josephson effect in a graphene sample with three
superconducting terminals. We observe robust fractional
Shapiro steps and correlated switching events, which can
only be explained by considering the device as a completely
connected Josephson network. We successfully simulate the
observed behaviors using a modified two-dimensional RCSJ

Abstract = {Nonequilibrium properties of correlated quantum matter are
being intensively investigated because of the rich interplay
between external driving and the many-body correlations. Of
particular interest is the nonequilibrium behavior near a
quantum critical point (QCP), where the system is delicately
balanced between different ground states. We present both an
analytical calculation of the nonequilibrium steady-state
current in a critical system and experimental results to
which the theory is compared. The system is a quantum dot
coupled to resistive leads: a spinless resonant level
interacting with an ohmic dissipative environment. A
two-channel Kondo-like QCP occurs when the level is on
resonance and symmetrically coupled to the leads, conditions
achieved by fine tuning using electrostatic gates. We
calculate and measure the nonlinear current as a function of
bias (I−V curve) at the critical values of the gate
voltages corresponding to the QCP. The quantitative
agreement between the experimental data and the theory, with
no fitting parameter, is excellent. As our system is fully
accessible to both theory and experiment, it provides an
ideal setting for addressing nonequilibrium phenomena in
correlated quantum matter.},

Abstract = {The resonant-level model represents a paradigmatic quantum
system which serves as a basis for many other quantum
impurity models. We provide a comprehensive analysis of the
nonequilibrium transport near a quantum phase transition in
a spinless dissipative resonant-level model, extending
earlier work. A detailed derivation of a rigorous mapping of
our system onto an effective Kondo model is presented. A
controlled energy-dependent renormalization-group approach
is applied to compute the nonequilibrium current in the
presence of a finite bias voltage V. In the linear-response
regime V→0, the system exhibits as a function of the
dissipative strength a localized-delocalized quantum
transition of the Kosterlitz-Thouless (KT) type. We address
fundamental issues of the nonequilibrium transport near the
quantum phase transition: Does the bias voltage play the
same role as temperature to smear out the transition? What
is the scaling of the nonequilibrium conductance near the
transition? At finite temperatures, we show that the
conductance follows the equilibrium scaling for V<T, while
it obeys a distinct nonequilibrium profile for V>T. We
furthermore provide different signatures of the transition
in the finite-frequency current noise and ac conductance via
a recently developed functional renormalization group (FRG)
approach. The generalization of our analysis to
nonequilibrium transport through a resonant level coupled to
two chiral Luttinger liquid leads, generated by fractional
quantum Hall edge states, is discussed. Our work on the
dissipative resonant level has direct relevance to
experiments on a quantum dot coupled to a resistive

Abstract = {There has been a growing interest in hybrid quantum
Hall-superconductor devices, driven by the prospect to
realize exotic ground states and excitations with
non-Abelian exchange statistics. While the existing
experiments clearly demonstrate Andreev coupling between the
edge states and the superconductors, the question remains
whether the quantum coherence could propagate between
several superconducting contacts via chiral channels. To
answer this question, we have first extended the
Landauer-Büttiker (LB) formalism to samples with one
superconducting contact and found a remarkable agreement
within a series of measurements related to each other via
LB-type formulas. We have then switched to the case of
multiple superconducting contacts, and found that we can
describe the measurements self-consistently if we neglect
the superconducting phase coherence between multiple
contacts. We interpret this result as a negative answer to
the question posed above: the phase correlations between
multiple superconducting contacts are not established via
μm-long quantum Hall edge states. Looking forward, our
approach may find applications in the broader field of
topological superconductivity and proximal structures.
Possible violations of the self-consistency tests presented
here may be used as an indication that superconducting phase
coherence is induced in the quantum Hall
edges.},

Abstract = {Superconducting diodes are proposed nonreciprocal circuit
elements that should exhibit nondissipative transport in one
direction while being resistive in the opposite direction.
Multiple examples of such devices have emerged in the past
couple of years; however, their efficiency is typically
limited, and most of them require a magnetic field to
function. Here we present a device that achieves
efficiencies approaching 100% while operating at zero field.
Our samples consist of a network of three graphene Josephson
junctions linked by a common superconducting island, to
which we refer as a Josephson triode. The three-terminal
nature of the device inherently breaks the inversion
symmetry, and the control current applied to one of the
contacts breaks the time-reversal symmetry. The triode's
utility is demonstrated by rectifying a small (nA scale
amplitude) applied square wave. We speculate that devices of
this type could be realistically employed in the modern
quantum circuits.},

Abstract = {A quantum phase transition is an abrupt change between two
distinct ground states of a many-body system, driven by an
external parameter. In the vicinity of the quantum critical
point (QCP) where the transition occurs, a new phase may
emerge that is determined by quantum fluctuations and is
very different from either phase. In particular, a
conducting system may exhibit non-Fermi-liquid behaviour.
Although this scenario is well established theoretically,
controllable experimental realizations are rare. Here, we
experimentally investigate the nature of the QCP in a simple
nanoscale system - a spin-polarized resonant level coupled
to dissipative contacts. We fine-tune the system to the QCP,
realized exactly on-resonance and when the coupling between
the level and the two contacts is symmetric. Several
anomalous transport scaling laws are demonstrated, including
a striking non-Fermi-liquid scattering rate at the QCP,
indicating fractionalization of the resonant level into two
Majorana quasiparticles. © 2013 Macmillan Publishers

the electrons tunneling across the nanotube, thus
suppressing the tunneling rate. We study the shape of the
resonant peak in the nanotube conductance, with the
expectation that the peak width and height, both dependent
on the tunneling rate, will be suppressed. Instead, we find
that the behavior crucially depends on the ratio of the
tunneling rates from the resonant level to the two contacts.
We discuss the implication of our findings for a boundary

Abstract = {A Luttinger liquid is an interacting one-dimensional
electronic system, quite distinct from the 'conventional'
Fermi liquids formed by interacting electrons in two and
three dimensions. Some of the most striking properties of
Luttinger liquids are revealed in the process of electron
tunnelling. For example, as a function of the applied bias
voltage or temperature, the tunnelling current exhibits a
non-trivial power-law suppression. (There is no such
suppression in a conventional Fermi liquid.) Here, using a
carbon nanotube connected to resistive leads, we create a
system that emulates tunnelling in a Luttinger liquid, by
controlling the interaction of the tunnelling electron with
its environment. We further replace a single tunnelling
barrier with a double-barrier, resonant-level structure and
investigate resonant tunnelling between Luttinger liquids.
At low temperatures, we observe perfect transparency of the
resonant level embedded in the interacting environment, and
the width of the resonance tends to zero. We argue that this
behaviour results from many-body physics of interacting
electrons, and signals the presence of a quantum phase
transition. Given that many parameters, including the
interaction strength, can be precisely controlled in our
samples, this is an attractive model system for studying
quantum critical phenomena in general, with wide-reaching
implications for understanding quantum phase transitions in
more complex systems, such as cold atoms and strongly
correlated bulk materials.},

narrow Al nanowires. The nanowires have a cross section as
small as 50 nm2. We focus on the retrapping current in a
down-sweep of the current, at which a nanowire re-enters the
superconducting state from a normal state. The retrapping
current is found to be significantly smaller than the
switching current at which the nanowire switches into the
normal state from a superconducting state during a current
up-sweep. For wires of different lengths, we analyze the
heat removal due to various processes, including electron
and phonon processes. For a short wire 1.5μm in length,
electronic thermal conduction is effective; for longer wires
10μm in length, phonon conduction becomes important. We
demonstrate that the measured retrapping current as a
function of temperature can be quantitatively accounted for
by the self-heating occurring in the normal portions of the
nanowires to better than 20% accuracy. For the phonon
processes, the extracted thermal conduction parameters
support the notion of a reduced phase-space below three
dimensions, consistent with the phonon thermal wavelength
having exceeded the lateral dimensions at temperatures below
∼1.3 K. Nevertheless, surprisingly the best fit was
achieved with a functional form corresponding to

For sufficiently open contacts, Kondo behavior is observed
for 1, 2, and 3 electrons in the topmost shell. As the
contacts are opened more, the sample enters the "mixed
valence" regime, where different charge states are strongly
hybridized by electron tunneling. Here, the conductance as a
function of gate voltage shows pronounced modulations with a
period of four electrons, and all single-electron features
are washed away at low temperature. We successfully describe
this behavior by a simple formula with no fitting
parameters. Finally, we find a surprisingly small energy
scale that controls the temperature evolution of conductance
and the tunneling density of states in the mixed valence

Superconducting contacts prevent out-diffusion of hot

channel for thermal relaxation. As local thermometers, we
use the amplitude of the universal conductance fluctuations,
which varies monotonically as a function of temperature. By
measuring the electron temperature simultaneously along the

competition between electron-phonon cooling and lateral heat
flow.},

Abstract = {Coupling superconductors to quantum Hall edge states is the
subject of intense investigation as part of the ongoing
search for non-abelian excitations. Our group has previously
observed supercurrents of hundreds of picoamperes in
graphene Josephson junctions in the quantum Hall regime. One
of the explanations of this phenomenon involves the coupling
of an electron edge state on one side of the junction to a
hole edge state on the opposite side. In our previous
samples, these states are separated by several microns.
Here, a narrow trench perpendicular to the contacts creates
counterpropagating quantum Hall edge channels tens of
nanometres from each other. Transport measurements
demonstrate a change in the low-field Fraunhofer
interference pattern for trench devices and show a
supercurrent in both trench and reference junctions in the
quantum Hall regime. The trench junctions show no
enhancement of quantum Hall supercurrent and an unexpected
supercurrent periodicity with applied field, suggesting the
need for further optimization of device parameters.},

Fluctuations in I(s) exhibit three distinct regions of

well below the critical temperature T(c), an increase as
T(2/3) at intermediate temperatures, and a rapid decrease
close to T(c). Heat dissipation analysis indicates that a
single phase slip is able to trigger switching at low and
intermediate temperatures, whereby the T(2/3) dependence
arises from the thermal activation of a phase slip, while
saturation at low temperatures provides striking evidence
that the phase slips by macroscopic quantum
tunneling.},

Abstract = {We study tunneling through a resonant level connected to two
dissipative bosonic baths: one is the resistive environment
of the source and drain leads, while the second comes from
coupling to potential fluctuations on a resistive gate. We
show that several quantum phase transitions (QPT) occur in
such a model, transitions which emulate those found in
interacting systems such as Luttinger liquids or Kondo
systems. We first use bosonization to map this dissipative
resonant level model to a resonant level in a Luttinger
liquid, one with, curiously, two interaction parameters.
Drawing on methods for analyzing Luttinger liquids at both
weak and strong coupling, we obtain the phase diagram. For
strong dissipation, a Berezinsky-Kosterlitz-Thouless QPT
separates strong-coupling and weak-coupling (charge
localized) phases. In the source-drain symmetric case, all
relevant backscattering processes disappear at strong
coupling, leading to perfect transmission at zero
temperature. In fact, a QPT occurs as a function of the
coupling asymmetry or energy of the resonant level: the two
phases are (i) the system is cut into two disconnected
pieces (zero transmission), or (ii) the system is a single
connected piece with perfect transmission, except for a
disconnected fractional degree of freedom. The latter arises
from the competition between the two fermionic leads (source
and drain), as in the two-channel Kondo effect. © 2014

Abstract = {The AC Josephson effect manifests itself in the form of
"Shapiro steps" of quantized voltage in Josephson junctions
subject to radiofrequency (RF) radiation. This effect
presents an early example of a driven-dissipative quantum
phenomenon and is presently utilized in primary voltage
standards. Shapiro steps have also become one of the
standard tools to probe junctions made in a variety of novel
materials. Here we study Shapiro steps in a widely tunable
graphene-based Josephson junction in which the
high-frequency dynamics is determined by the on-chip
environment. We investigate the variety of patterns that can
be obtained in this well-understood system depending on the
carrier density, temperature, RF frequency, and magnetic
field. Although the patterns of Shapiro steps can change
drastically when just one parameter is varied, the overall
trends can be understood and the behaviors straightforwardly
simulated, showing some key differences from the
conventional RCSJ model. The resulting understanding may
help interpret similar measurements in more complex
materials.},

Abstract = {We present numerical renormalization group calculations for
the zero-bias conductance of quantum dots made from
semiconducting carbon nanotubes. These explain and reproduce
the thermal evolution of the conductance for different
groups of orbitals, as the dot-lead tunnel coupling is
varied and the system evolves from correlated Kondo behavior
to more weakly correlated regimes. For integer fillings N=1,
2, 3 of an SU(4) model, we find universal scaling behavior
of the conductance that is distinct from the standard SU(2)
universal conductance, and concurs quantitatively with
experiment. Our results also agree qualitatively with
experimental differential conductance maps.},

Title = {Anisotropic Superconductivity at Epitaxial KTaO3(111)
interfaces},
Journal = {submitted to Science Advances},
Year = {2022},
Abstract = {A two-dimensional, anisotropic superconductivity was
recently discovered at the KTaO3 (111) interfaces. The
nature of the anisotropic superconducting transition remains
a subject of debate. To investigate the origins of the
observed behavior, we grew epitaxial LaSrMnO3/KTaO3(111)
het- erostructures. We show that the superconductivity is
robust against the in-plane magnetic field and violates the
Pauli limit. We also show that the Cooper pairs are more
resilient when the bias is along [11 ̄2] (I ∥ [11 ̄2])
and the magnetic field is along [1 ̄10] (B ∥ [1 ̄10]).
We discuss the anisotropic nature of superconductivity in
the context of electronic structure, orbital character, and
spin texture at the KTaO3 (111) interfaces. The results
point to new opportunities to enhance superconducting tran-
sition temperatures and critical fields in crystalline,
two-dimensional superconductors with strong spin-orbit
coupling.},

Abstract = {We perform a systematic study of Andreev conversion at the
interface between a superconductor and graphene in the
quantum Hall (QH) regime. We find that the probability of
Andreev conversion from electrons to holes follows an
unexpected but clear trend: the dependencies on temperature
and magnetic field are nearly decoupled. We discuss these
trends and the role of the superconducting vortices, whose
normal cores could both absorb and dephase the individual
electrons in a QH edge. Our Letter may pave the road to
engineering a future generation of hybrid devices for
exploiting superconductivity proximity in chiral
channels.},

Month = {December},
url = {https://arxiv.org/abs/2212.13952},
Abstract = {A Josephson junction subject to an external RF excitation
may experience the inverse AC Josephson effect, where the
phase across the junction locks to the drive. The resulting
``Shapiro steps'' of quantized voltage are currently
utilized in primary voltage standards. The effect has also
been a key technique in the search for topological
superconductivity. Here, we study a particularly interesting
regime in which the zero voltage state becomes unstable at
zero DC bias, and the junction spontaneously develops the
first Shapiro step with a voltage V=±ℏω/2e. The
switching time between the +ℏω/2e and −ℏω/2e states
ranges from milliseconds to hours. Most interestingly, we
find a surprising regime with a non-monotonic temperature
dependence, in which the switching time demonstrates a
pronounced minimum at intermediate temperatures. Tuning of
the measurement parameters is also shown to give rise to a
tristable switching behavior, showcasing the potential for
further experiments in stochastic physics and quantum
thermodynamics.},

Title = {Non-local transport measurements in hybrid quantum Hall -
superconducting devices},
Year = {2023},
Month = {October},
Abstract = {We develop the expressions for the non-local resistances of
hybrid quantum Hall -- superconductor devices. Our
approximation depends on the crucial assumption that the
superconducting phase correlations between contacts do not
play a role. We verify the validity of our approach in two
devices: in the first one, a single superconducting contact
couples to multiple edge states, while in the second, there
are multiple superconducting electrodes. The results
obtained for the second device suggest that the
superconducting phase coherence is not maintained over our
micron-scale graphene devices. Possible violations of this
assumption may be used as an indication that superconducting
phase coherence is induced in quantum Hall
edges.},

Josephson Triode},
Year = {2022},
Month = {October},
url = {https://arxiv.org/abs/2210.02644},
Abstract = {Superconducting diodes are proposed non-reciprocal circuit
elements that should exhibit non-dissipative transport in
one direction while being resistive in the opposite
direction. Multiple examples of such devices have emerged in
the past couple of years, however their efficiency is
typically limited, and most of them require magnetic field
to function. Here we present a device achieving efficiencies
upwards of 90% while operating at zero field. Our samples
consist of a network of three graphene Josephson junctions
linked by a common superconducting island, to which we refer
as a Josephson triode. The triode is tuned by applying a
control current to one of the contacts, thereby breaking the
time-reversal symmetry of the current flow. The triode's
utility is demonstrated by rectifying a small (tens of nA
amplitude) applied square wave. We speculate that devices of
this type could be realistically employed in the modern
quantum circuits.},
