WSe2 light-emitting tunneling transistors with enhanced brightness at room temperature
F. Withers, O. Del Pozo-Zamudio, S. Schwarz +15
Monolayers of molybdenum and tungsten dichalcogenides are direct bandgap semiconductors, which makes them promising for opto-electronic applications. In particular, van der Waals h…
Fast relaxation of photo-excited carriers in 2D transition metal dichalcogenides
Mark Danovich, Igor Aleiner, Neil D. Drummond +1
We predict a fast relaxation of photo-excited carriers in monolayer transition metal dichalcogenides (TMDCs), which is mediated by the emission of longitudinal optical (LO) phonons…
Turning the BEC-BCS crossover into a transition by radiation
Y. Lemonik, I. L. Aleiner, B. L. Altshuler
We show that the Bardeen-Cooper-Schrieffer state (BCS) and the Bose-Einstein condensation (BEC) sides of the BCS-BEC crossover can be rigorously distinguished from each other by th…
Non-analytic Vortex Core and a Nonlinear Vortex Flow in Bosonic Superfluids
Oded Agam, Igor L. Aleiner
We analyze the disorder limited motion of quantum vortices in a two-dimensional bosonic superfluid with a large healing length. It is shown that the excitations of low-energy degre…
Finite-Temperature Fluid-Insulator Transition of Strongly Interacting 1D Disordered Bosons
V. P. Michal, I. L. Aleiner, B. L. Altshuler +1
We consider the many-body localization-delocalization transition for strongly interacting one- dimensional disordered bosons and construct the full picture of finite temperature be…
