Dynamics of topological defects after a photo-induced melting of a charge-density wave
Andrei E. Tarkhov, A. V. Rozhkov, Alfred Zong +3
Charge-density-wave order in a solid can be temporarily "melted" by a strong laser pulse. Here we use the discrete Gross-Pitaevskii equation on a cubic lattice to simulate the reco…
Transient ordering in the Gross-Pitaevskii lattice subject to an energy quench within the disordered phase
Andrei E. Tarkhov, A. V. Rozhkov, Boris V. Fine
We numerically investigate heating-and-cooling quenches taking place entirely in the non-ordered phase of the discrete Gross-Pitaevskii equation on a three-dimensional cubic lattic…
Phase coherent electron transport in asymmetric cross-like Andreev interferometers
Pavel E. Dolgirev, Mikhail S. Kalenkov, Andrei E. Tarkhov +1
We present a detailed theoretical description of quantum coherent electron transport in voltage-biased cross-like Andreev interferometers. Making use of the charge conjugation symm…
Estimating ergodization time of a chaotic many-particle system from a time reversal of equilibrium noise
Andrei E. Tarkhov, Boris V. Fine
We propose a method of estimating ergodization time of a chaotic many-particle system by monitoring equilibrium noise before and after time reversal of dynamics (Loschmidt echo). T…
Extracting Lyapunov exponents from the echo dynamics of Bose-Einstein condensates on a lattice
Andrei E. Tarkhov, Sandro Wimberger, Boris V. Fine
We propose theoretically an experimentally realizable method to demonstrate the Lyapunov instability and to extract the value of the largest Lyapunov exponent for a chaotic many-pa…
Universality of the Berezinskii-Kosterlitz-Thouless type of phase transition in the dipolar XY-model
A. Yu. Vasiliev, A. E. Tarkhov, L. I. Menshikov +2
We investigate the nature of the phase transition occurring in a planar XY-model spin system with dipole-dipole interactions. It is demonstrated that a Berezinskii-Kosterlitz-Thoul…
