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…
Quantum ratchet driven by broadband perturbation
D. V. Makarov, L. E. Kon'kov
Motion of an atomic ensemble trapped into a deep optical lattice is considered. We propose a novel approach to construct an atomic ratchet by superimposing two additional lattices…
Study of wave chaos in a randomly-inhomogeneous oceanic acoustic waveguide: spectral analysis of the finite-range evolution operator
D. V. Makarov, L. E. Kon'kov, M. Yu. Uleysky +1
The proplem of sound propagation in an oceanic waveguide is considered. Scattering on random inhomogeneity of the waveguide leads to wave chaos. Chaos reveals itself in spectral pr…
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.…
