Random matrix theory for low-frequency sound propagation in the ocean: a spectral statistics test
Denis Makarov
Problem of long-range sound propagation in the randomly-inhomogeneous deep ocean is considered. We examine a novel approach for modeling of wave propagation, developed by K.C.Hegew…
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…
Control of atomic transport using autoresonance
D. V. Makarov, M. Yu. Uleysky, S. V. Prants
Dynamics of an atomic wavepacket in an optical superlattice is considered. We propose a simple scheme of wavepacket localization near the minima of the optical potential. In our ap…
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…
