In the 1990s, the study of the chaotic behavior of ray trajectories in inhomogeneous
waveguides emerged as a new field in ocean acoustics. It turned out that at ranges on the …

Возможность распространения звука в океане на расстояния порядка нескольких сотен
и даже тысяч километров обусловлена существованием рефракционного волновода …

We study the dependence of the chaotic layer width in spatially periodic non-autonomous
Hamiltonian systems on the waveform of adiabatic ac time-periodic forces. Contrary to …

Рассмотрена задача о рассеянии модовых акустических импульсов на синоптических
вихрях с учётом влияния поля внутренних волн. Использован лучевой формализм в …

In this paper we study how deterministic features presented by a system can be used to
perform direct transport in a quasisymmetric potential and weak dissipative system. We …

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 …

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 localized …

The motion of a randomly driven quantum nonlinear pendulum is considered. Utilizing a one-
step Poincaré map, we demonstrate that the classical phase space corresponding to a …

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 …

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 …
