Quantum transport in a driven disordered potential: onset of directed current and noise-induced current reversal
Denis Makarov, Leonid Kon'kov
We study motion of a quantum wavepacket in a one-dimensional potential with correlated disorder. Presence of long-range potential correlations allows for existence of both localize…
Order-to-chaos transition in the model of a quantum pendulum subjected to noisy perturbation
Denis Makarov, Leonid Kon'kov
Motion of randomly-driven quantum nonlinear pendulum is considered. Utilizing one-step Poincaré map, we demonstrate that classical phase space corresponding to a single realization…
Recovery of ordered periodic orbits with increasing wavelength for sound propagation in a range-dependent waveguide
L. E. Kon'kov, D. V. Makarov, E. V. Sosedko +1
We consider sound wave propagation in a range-periodic acoustic waveguide in the deep ocean. It is demonstrated that vertical oscillations of a sound-speed perturbation, induced by…
Level spacing statistics in a randomly-inhomogeneous acoustic waveguide
D. V. Makarov, L. E. Kon'kov, M. Yu. Uleysky
Dynamics of a randomly-perturbed quantum system with 3/2-degrees of freedom is considered. We introduce a transfer operator being the quantum analogue of the specific Poincaré map.…
