On twinning in smectic crystals
V. I. Marchenko
It is shown that mechanical twinning in smectic crystals is possible. The structure of the boundary of twins for a small disorientation of crystallites is determined. The periodic…
Study of the 4He crystal surface
K. O. Keshishev, V. I. Marchenko, D. B. Shemyatikhin
The evolution of the meniscus of a helium crystal near the (0001) face is traced during a change in the boundary conditions at the chamber wall in the temperature range 0.5-0.9 K.…
Localization properties of squeezed quantum states in nanoscale space domains
A. S. Trushechkin, I. V. Volovich
We construct families of squeezed quantum states on an interval (depending on boundary conditions, we interpret the interval as a circle or as the infinite square potential well) a…
Conservation laws in gravitational theories with general nonminimal coupling
Yuri N. Obukhov, Dirk Puetzfeld
We use the Lagrange-Noether methods to derive the conservation laws for models in which matter interacts nonminimally with the gravitational field. The nonminimal coupling function…
Semiclassical description of collapses and revivals of quantum wave packets in bounded domains
A. S. Trushechkin, I. V. Volovich
We study a special kind of semiclassical limit of quantum dynamics on a circle and in a box (infinite potential well with hard walls) as the Planck constant tends to zero and time…
Trap-free manipulation in the Landau-Zener system
Alexander Pechen, Nikolay Il'in
The analysis of traps, i.e., locally but not globally optimal controls, for quantum control systems has attracted a great interest in recent years. The central problem that has bee…
