   Abstract = {Coherent light sources have been demonstrated based on a
             wide range of nanostructures, however, little effort has
             been devoted to probing their underlying coherence
             properties. Here, we report long-range spatial coherence of
             lattice plasmon lasers constructed from a periodic array of
             gold nanoparticles and a liquid gain medium at room
             temperature. By combining spatial and temporal
             interferometry, we demonstrate millimeter-scale (∼1 mm)
             spatial coherence and picosecond (∼2 ps) temporal
             coherence. The long-range spatial coherence occurs even
             without the presence of strong coupling with the lattice
             plasmon mode extending over macroscopic distances in the
             lasing regime. This plasmonic lasing system thus provides a
             platform for understanding the emergence of long-range
             coherence from collections of nanoscale resonators and
             points toward novel types of distributed lasing
             sources.},

   Abstract = {The creation of energetic electrons through plasmon
             excitation of nanostructures before thermalization has been
             proposed for a wide number of applications in optical energy
             conversion and ultrafast nanophotonics. However, the use of
             "nonthermal" electrons is primarily limited by both a low
             generation efficiency and their ultrafast decay. We report
             experimental and theoretical results on the use of broadband
             plasmonic nanopatch metasurfaces comprising a gold substrate
             coupled to silver nanocubes that produce large
             concentrations of hot electrons, which we measure using
             transient absorption spectroscopy. We find evidence for
             three subpopulations of nonthermal carriers, which we
             propose arise from anisotropic electron-electron scattering
             within sp-bands near the Fermi surface. The bimetallic
             character of the metasurface strongly impacts the physics,
             with dissipation occurring primarily in the gold, whereas
             the quantum process of hot electron generation takes place
             in both components. Our calculations show that the choice of
             geometry and materials is crucial for producing strong
             ultrafast nonthermal electron components.The creation of
             energetic electrons through plasmon excitation has
             implications in optical energy conversion and ultrafast
             nanophotonics. Here, the authors find evidence for three
             subpopulations of nonthermal carriers which arise from
             anisotropic electron-electron scattering near the Fermi
             surface.},

   Abstract = {We present a method for colloidal synthesis of silver
             nanocubes and the use of these in combination with a smooth
             gold film, to fabricate plasmonic nanoscale patch antennas.
             This includes a detailed procedure for the fabrication of
             thin films with a well-controlled thickness over macroscopic
             areas using layer-by-layer deposition of polyelectrolyte
             polymers, namely poly(allylamine) hydrochloride (PAH) and
             polystyrene sulfonate (PSS). These polyelectrolyte spacer
             layers serve as a dielectric gap in between silver nanocubes
             and a gold film. By controlling the size of the nanocubes or
             the gap thickness, the plasmon resonance can be tuned from
             about 500 nm to 700 nm. Next, we demonstrate how to
             incorporate organic sulfo-cyanine5 carboxylic acid (Cy5) dye
             molecules into the dielectric polymer gap region of the
             nanopatch antennas. Finally, we show greatly enhanced
             fluorescence of the Cy5 dyes by spectrally matching the
             plasmon resonance with the excitation energy and the Cy5
             absorption peak. The method presented here enables the
             fabrication of plasmonic nanopatch antennas with
             well-controlled dimensions utilizing colloidal synthesis and
             a layer-by-layer dip-coating process with the potential for
             low cost and large-scale production. These nanopatch
             antennas hold great promise for practical applications, for
             example in sensing, ultrafast optoelectronic devices and for
             high-efficiency photodetectors.},

   Abstract = {Two-dimensional transition metal dichalcogenides (TMDCs)
             have spurred excitement for potential applications in
             optoelectronic and valleytronic devices; however, the origin
             of the dynamics of excitons, trions, and other localized
             states in these low dimensional materials is not
             well-understood. Here, we experimentally probed the dynamics
             of excitonic states in monolayer WSe2 by investigating the
             temperature and polarization dependent photoluminescence
             (PL) spectra. Four pronounced PL peaks were identified below
             a temperature of 60 K at near-resonant excitation and
             assigned to exciton, trion and localized states from
             excitation power dependence measurements. We find that the
             localized states vanish above 65 K, while exciton and
             trion emission peaks remain up to room temperature. This can
             be explained by a multi-level model developed for
             conventional semiconductors and applied to monolayer TMDCs
             for the first time here. From this model, we estimated a
             lower bound of the exciton binding energy of 198 meV for
             monolayer WSe2 and explained the vanishing of the localized
             states. Additionally, we observed a rapid decrease in the
             degree of circular polarization of the PL at increasing
             temperatures indicating a relatively strong electron-phonon
             coupling and impurity-related scattering. Our results reveal
             further insight into the excitonic states in monolayer WSe2
             which is critical for future practical applications.},

   Abstract = {Optical cavities with multiple tunable resonances have the
             potential to provide unique electromagnetic environments at
             two or more distinct wavelengths--critical for control of
             optical processes such as nonlinear generation, entangled
             photon generation, or photoluminescence (PL) enhancement.
             Here, we show a plasmonic nanocavity based on a nanopatch
             antenna design that has two tunable resonant modes in the
             visible spectrum separated by 350 nm and with line widths of
             ∼60 nm. The importance of utilizing two resonances
             simultaneously is demonstrated by integrating monolayer
             MoS2, a two-dimensional semiconductor, into the colloidally
             synthesized nanocavities. We observe a 2000-fold enhancement
             in the PL intensity of MoS2--which has intrinsically low
             absorption and small quantum yield--at room temperature,
             enabled by the combination of tailored absorption
             enhancement at the first harmonic and PL quantum-yield

   Abstract = {Plasmon lasers can support ultrasmall mode confinement and
             ultrafast dynamics with device feature sizes below the
             diffraction limit. However, most plasmon-based nanolasers
             rely on solid gain materials (inorganic semiconducting
             nanowire or organic dye in a solid matrix) that preclude the
             possibility of dynamic tuning. Here we report an approach to
             achieve real-time, tunable lattice plasmon lasing based on
             arrays of gold nanoparticles and liquid gain materials.
             Optically pumped arrays of gold nanoparticles surrounded by
             liquid dye molecules exhibit lasing emission that can be
             tuned as a function of the dielectric environment.
             Wavelength-dependent time-resolved experiments show distinct
             lifetime characteristics below and above the lasing
             threshold. By integrating gold nanoparticle arrays within
             microfluidic channels and flowing in liquid gain materials
             with different refractive indices, we achieve dynamic tuning
             of the plasmon lasing wavelength. Tunable lattice plasmon
             lasers offer prospects to enhance and detect weak physical
             and chemical processes on the nanoscale in real

   Abstract = {The radiative processes associated with fluorophores and
             other radiating systems can be profoundly modified by their
             interaction with nanoplasmonic structures. Extreme
             electromagnetic environments can be created in plasmonic
             nanostructures or nanocavities, such as within the nanoscale
             gap region between two plasmonic nanoparticles, where the
             illuminating optical fields and the density of radiating
             modes are dramatically enhanced relative to vacuum.
             Unraveling the various mechanisms present in such coupled
             systems, and their impact on spontaneous emission and other
             radiative phenomena, however, requires a suitably reliable
             and precise means of tuning the plasmon resonance of the
             nanostructure while simultaneously preserving the
             electromagnetic characteristics of the enhancement region.
             Here, we achieve this control using a plasmonic platform
             consisting of colloidally synthesized nanocubes
             electromagnetically coupled to a metallic film. Each
             nanocube resembles a nanoscale patch antenna (or nanopatch)
             whose plasmon resonance can be changed independent of its
             local field enhancement. By varying the size of the
             nanopatch, we tune the plasmonic resonance by ∼ 200 nm,
             encompassing the excitation, absorption, and emission
             spectra corresponding to Cy5 fluorophores embedded within
             the gap region between nanopatch and film. By sweeping the
             plasmon resonance but keeping the field enhancements roughly
             fixed, we demonstrate fluorescence enhancements exceeding a
             factor of 30,000 with detector-limited enhancements of the
             spontaneous emission rate by a factor of 74. The experiments
             are supported by finite-element simulations that reveal
             design rules for optimized fluorescence enhancement or large
             Purcell factors.},

   Abstract = {Plasmonics takes advantage of the properties of surface
             plasmon polaritons, which are localized or propagating
             quasiparticles in which photons are coupled to the
             quasi-free electrons in metals. In particular, plasmonic
             devices can confine light in regions with dimensions that
             are smaller than the wavelength of the photons in free
             space, and this makes it possible to match the different
             length scales associated with photonics and electronics in a
             single nanoscale device. Broad applications of plasmonics
             that have been demonstrated to date include biological
             sensing, sub-diffraction-limit imaging, focusing and
             lithography and nano-optical circuitry. Plasmonics-based
             optical elements such as waveguides, lenses, beamsplitters
             and reflectors have been implemented by structuring metal
             surfaces or placing dielectric structures on metals to
             manipulate the two-dimensional surface plasmon waves.
             However, the abrupt discontinuities in the material
             properties or geometries of these elements lead to increased
             scattering of surface plasmon polaritons, which
             significantly reduces the efficiency of these components.
             Transformation optics provides an alternative approach to
             controlling the propagation of light by spatially varying
             the optical properties of a material. Here, motivated by
             this approach, we use grey-scale lithography to
             adiabatically tailor the topology of a dielectric layer
             adjacent to a metal surface to demonstrate a plasmonic
             Luneburg lens that can focus surface plasmon polaritons. We
             also make a plasmonic Eaton lens that can bend surface
             plasmon polaritons. Because the optical properties are
             changed gradually rather than abruptly in these lenses,
             losses due to scattering can be significantly reduced in
             comparison with previously reported plasmonic elements. ©

   Abstract = {Plasmonics takes advantage of the properties of surface
             plasmon polaritons, which are localized or propagating
             quasiparticles in which photons are coupled to the
             quasi-free electrons in metals. In particular, plasmonic
             devices can confine light in regions with dimensions that
             are smaller than the wavelength of the photons in free
             space, and this makes it possible to match the different
             length scales associated with photonics and electronics in a
             single nanoscale device. Broad applications of plasmonics
             that have been demonstrated to date include biological
             sensing, sub-diffraction-limit imaging, focusing and
             lithography and nano-optical circuitry. Plasmonics-based
             optical elements such as waveguides, lenses, beamsplitters
             and reflectors have been implemented by structuring metal
             surfaces or placing dielectric structures on metals to
             manipulate the two-dimensional surface plasmon waves.
             However, the abrupt discontinuities in the material
             properties or geometries of these elements lead to increased
             scattering of surface plasmon polaritons, which
             significantly reduces the efficiency of these components.
             Transformation optics provides an alternative approach to
             controlling the propagation of light by spatially varying
             the optical properties of a material. Here, motivated by
             this approach, we use grey-scale lithography to
             adiabatically tailor the topology of a dielectric layer
             adjacent to a metal surface to demonstrate a plasmonic
             Luneburg lens that can focus surface plasmon polaritons. We
             also make a plasmonic Eaton lens that can bend surface
             plasmon polaritons. Because the optical properties are
             changed gradually rather than abruptly in these lenses,
             losses due to scattering can be significantly reduced in
             comparison with previously reported plasmonic elements. ©

   Abstract = {Most schemes for quantum information processing require fast
             single qubit operations as well as initialization and
             read-out steps. Here we describe recent experimental
             realizations of schemes for time-resolved initialization,
             coherent control, and read-out of a single electron spin
             state in an individual quantum dot using all-optical
             techniques. The spin state is manipulated via the optical
             Stark effect using off-resonant, picosecond-scale optical
             pulses. The coherent rotation of a single electron spin
             state through arbitrary angles up to π radians is
             demonstrated, constituting a single qubit gate. This spin
             manipulation is directly monitored using time-resolved Kerr
             rotation spectroscopy allowing for the observation of the
             coherent evolution of a single electron spin state in time
