Bethe Ansatz Solutions for Certain Periodic Quantum Circuits
I. L. Aleiner
I derived Bethe Ansatz equations for two model Periodic Quantum Circuits: 1) XXZ model; 2) Chiral Hubbard Model. I obtained explicit expressions for the spectra of the strings of a…
New exact results for the two-phase model with several conserved currents
Oded Agam, Igor L Aleiner, Dror Orgad
We consider the macroscopic transport properties of two-dimensional random binary mixtures with identical spatial distributions of the two phases. Previous studies have obtained ex…
Excess resistivity in graphene superlattices caused by umklapp electron-electron scattering
J. R. Wallbank, R. Krishna Kumar, M. Holwill +11
Umklapp processes play a fundamental role as the only intrinsic mechanism that allows electrons to transfer momentum to the crystal lattice and, therefore, provide a finite electri…
Transient superconductivity without superconductivity
Giuliano Chiriacò, Andrew J. Millis, Igor L. Aleiner
Recent experiments on KC and layered copper-oxide materials have reported substantial changes in the optical response following application of an intense THz pulse. Thes…
Auger recombination of dark excitons in and monolayers
Mark Danovich, Viktor Zólyomi, Igor L. Aleiner +1
We propose a novel phonon assisted Auger process unique to the electronic band structure of monolayer transition metal dichalcogenides (TMDCs), which dominates the radiative recomb…
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…
Aharonov-Bohm Oscillations in Singly-Connected Disordered Conductors

We show that transport and thermodynamic properties of \emph{singly-connected} disordered conductors exhibit quantum Aharonov - Bohm oscillations with the total magnetic flux throu…

Bogdan Ganchev, Neil Drummond, Igor Aleiner +1
We map the three-body problem in two dimensions onto one particle in a three dimensional potential treatable by a purposely-developed boundary-matching-matrix method. We evaluate b…
Quantum Memory Effects in Disordered Systems and Their Relation to 1/f Noise
Yonah Lemonik, Igor Aleiner
We propose that memory effects in the conductivity of metallic systems can be produced by the same two levels systems that are responsible for the 1/f noise. Memory effects are ext…
Localization at the Edge of 2D Topological Insulator by Kondo Impurities with Random Anisotropies
B. L. Altshuler, I. L. Aleiner, V. I. Yudson
We consider chiral electrons moving along the 1D helical edge of a 2D topological insulator and interacting with a disordered chain of Kondo impurities. Assuming the electron-spin…
Radiative coupling and weak lasing of exciton-polariton condensates
I. L. Aleiner, B. L. Altshuler, Y. G. Rubo
In spite of having finite life-time exciton-polaritons in microcavities are known to condense at strong enough pumping of the reservoir. We present an analytical theory of such Bos…

Spontaneous symmetry breakings in graphene subjected to in-plane magnetic field
I. L. Aleiner, D. E. Kharzeev, A. M. Tsvelik
Application of the magnetic field parallel to the plane of the graphene sheet leads to the formation of electron- and hole-like Fermi surfaces. Such situation is shown to be unstab…

Transport in undoped graphene is related to percolating current patterns in the networks of {\em N-} and {\em P}-type regions reflecting the strong bipolar charge density fluctuati…
