   Abstract = {<jats:p>This paper studies the role of expectations in
             driving export adjustment. We assemble bilateral data on
             spot exchange rates, one year ahead exchange rate forecasts
             and HS2-product export data for 11 exporting countries and
             64 destinations, covering the 2006–2014 period. Results
             from fixed effects regressions and an instrumental variables
             approach show that expectations of exchange rate changes are
             an important channel for export adjustment. A one percent
             expected exchange rate depreciation over the next year is
             associated with a 0.96 percent increase in the extensive
             margin (entry of new exporters) in the 2SLS regression, with
             statistically insignificant effects on total exports or the
             intensive margin. We provide intuition for these findings
             with a simple model with heterogeneous firms and sticky
             prices, and use our model to discuss the implications of
             anticipation for subsequent export growth and trade

             and the challenges of, integrating visual arts and online
             art museum visits into CFL teaching. Quantitative and

   Abstract = {Controlling electron transfer (ET) processes in
             donor-bridge-acceptor (DBA) compounds by mid-IR excitation
             can enhance our understanding of the ET dynamics and may
             find practical applications in molecular sensing and
             molecular-scale electronics. Alkyne moieties are attractive
             to serve as ET bridges, as they offer the possibility of
             fast ET and present convenient vibrational modes to perturb
             the ET dynamics. Yet, these bridges introduce complexity
             because of the strong torsion angle dependence of the ET
             rates and transition dipoles among electronic states and a
             shallow torsion barrier. In this study, we implemented
             ultrafast 3-pulse laser spectroscopy to investigate how the
             ET from the dimethyl aniline (D) electron donor to the
             <i>N</i>-isopropyl-1,8-napthalimide (NAP) electron acceptor
             can be altered by exciting the CC stretching mode
             (<i>ν</i><sub>CC</sub>) of the butadiyne bridge linking
             the donor and acceptor. The electron transfer was initiated
             by electronically exciting the acceptor moiety at 400 nm,
             followed by vibrational excitation of the alkyne,
             <i>ν</i><sub>CC</sub>, and detecting the changes in the
             absorption spectrum in the visible spectral region. The
             experiments were performed at different delay times
             <i>t</i><sub>1</sub> and <i>t</i><sub>2</sub>, which are the
             delays between UV-mid-IR and mid-IR-Vis pulses,
             respectively. Two sets of torsion-angle conformers were
             identified, one featuring a very fast mean ET time of 0.63
             ps (group A) and another featuring a slower mean ET time of
             4.3 ps (group B), in the absence of the mid-IR excitation.
             TD-DFT calculations were performed to determine key torsion
             angle dependent molecular parameters, including the
             electronic and vibrational transition dipoles, transition
             frequencies, and electronic couplings. To describe the
             3-pulse data, we developed a kinetic model that includes a
             locally excited, acceptor-based S2 state, a charge separated
             S1 state, and their vibrationally excited counterparts, with
             either excited <i>ν</i><sub>CC</sub> (denoted as
             S1A<sup>tr</sup>, S1B<sup>tr</sup>, S2A<sup>tr</sup>, and
             S2B<sup>tr</sup>, where tr stands for the excited triplet
             bond, <i>ν</i><sub>CC</sub>) or excited daughter modes
             of the <i>ν</i><sub>CC</sub> relaxation
             (S1A<sup>h</sup>, S1B<sup>h</sup>, S2A<sup>h</sup>, and
             S2B<sup>h</sup>, where h stands for vibrationally hot
             species). The kinetic model was solved analytically, and the
             species-associated spectra (SAS) were determined numerically
             using a matrix approach, treating first the experiments with
             longer <i>t</i><sub>1</sub> delays and then using the
             already determined SAS for modeling the experiments with
             shorter <i>t</i><sub>1</sub> delays. Strong vibronic
             coupling of <i>ν</i><sub>CC</sub> and of vibrationally
             hot states makes the analysis complicated. Nevertheless, the
             SAS were identified and the ET rates of the vibrationally
             excited species, S2A<sup>tr</sup>, S2B<sup>tr</sup> and
             S2B<sup>h</sup>, were determined. The results show that the
             ET rate for the S2A species is <i>ca.</i> 1.2-fold slower
             when the <i>ν</i><sub>CC</sub> mode is excited. The ET
             rate for species S2B is slower by <i>ca.</i> 1.3-fold if the
             compound is vibrationally hot and is essentially unchanged
             when the <i>ν</i><sub>CC</sub> mode is excited. The SAS
             determined for the tr and h species resemble the SAS for
             their respective precursor species in the 2-pulse transient
             absorption experiments, which validates the procedure used
             and the results.},

   Abstract = {Chiral perovskite nanoparticles and films are promising for
             integration in emerging spintronic and optoelectronic
             technologies, yet few design rules exist to guide the
             development of chiral material properties. The chemical
             space of potential building blocks for these nanostructures
             is vast, and the mechanisms through which organic ligands
             can impart chirality to the inorganic perovskite lattice are
             not well understood. In this work, we investigate how the
             properties of chiral ammonium ligands, the most common
             organic ligand type used with perovskites, affect the
             circular dichroism of strongly quantum confined
             CsPbBr<sub>3</sub> nanocrystals. We show that aromatic
             ammonium ligands with stronger electron-donating groups lead
             to higher-intensity circular dichroism associated with the
             lowest-energy excitonic transition of the perovskite
             nanocrystal. We argue that this behavior is best explained
             by a modulation of the exciton wavefunction overlap between
             the nanocrystal and the organic ligand, as the functional
             groups on the ligand can shift electron density toward the
             organic species-perovskite lattice interface to increase the
             imprinting.},

             describes a quantum simulation method that explores the
             influence of light polarization on electron transfer between
             two molecules. By implementing precise and coherent control
             among the quantum states of trapped atomic ions, we can
             induce quantum dynamics that mimic the electron-transfer
             dynamics in molecules. We use three-level systems (qutrits),
             rather than traditional two-level systems (qubits), to
             enhance the simulation efficiency and realize high-fidelity
             simulations of electron-transfer dynamics. We treat the
             quantum interference between the electron coupling pathways
             from a donor with two degenerate excited states to an
             acceptor and analyze the transfer efficiency. We also
             examine the potential error sources that enter the quantum
             simulations. The trapped-ion systems have favorable scalings
             with system size compared to those of classical computers,

   Abstract = {Studies of biological transport frequently neglect the
             explicit statistical correlations among particle site
             occupancies (i.e., they use a mean-field approximation).
             Neglecting correlations sometimes captures biological
             function, even for out-of-equilibrium and interacting
             systems. We show that neglecting correlations fails to
             describe free energy transduction, mistakenly predicting an
             abundance of slippage and energy dissipation, even for
             networks that are near reversible and lack interactions
             among particle sites. Interestingly, linear charge transport
             chains are well described without including correlations,
             even for networks that are driven and include site-site
             interactions typical of biological electron transfer chains.
