Bose system critical dynamics near quantum phase transition
M. G. Vasin, V. M. Vinokur
We show that the change of the fluctuation spectrum near the quantum critical point (QCP) may result in the continuous change of critical exponents with temperature due to the incr…
Parity-time symmetry breaking in spin chains
Alexey Galda, Valerii M. Vinokur
We investigate nonequilibrium phase transitions in classical Heisenberg spin chains associated with spontaneous breaking of parity-time () symmetry of the system unde…
Berezinskii-Kosterlitz-Thouless and Vogel-Fulcher-Tammann criticality in model
M. G. Vasin, V. N. Ryzhov, V. M. Vinokur
We develop a gauge theory of the critical behavior of the topological excitations-driven Berezinskii-Kosterlitz-Thouless (BKT) phase transition in the XY model with weak quenched d…
Numerical study of the depinning transition of a ferromagnetic magnetic domain wall in films
Bin Xi, Meng-Bo Luo, Valerii M. Vinokur +1
We report first principle numerical study of domain wall (DW) depinning in two-dimensional magnetic film, which is modeled by 2D random-field Ising system with the dipole-dipole in…
Quantum Brownian motion in ratchet potentials
Stefan Scheidl, Valerii M. Vinokur
We investigate the dynamics of quantum particles in a ratchet potential subject to an ac force field. We develop a perturbative approach for weak ratchet potentials and force field…
Nonequilibrium dislocation dynamics and instability of driven vortex lattices in two dimensions
Igor S. Aranson, Stefan Scheidl, Valerii M. Vinokur
We consider dislocations in a vortex lattice that is driven in a two-dimensional superconductor with random impurities. The structure and dynamics of dislocations is studied in thi…
