Berry phase caused by nondissipative drag of superflow in a Bose qubit
D. V. Fil, S. I. Shevchenko
A microscopic theory of superfluid drag in a two-component Bose gas is developed. The drag factor is shown to be proportional to the square root of the gas parameter. Basing on the…

Drag of superfluid current in bilayer Bose systems
D. V. Fil, S. I. Shevchenko
An effect of nondissipative drag of a superfluid flow in a system of two Bose gases confined in two parallel quasi two-dimensional traps is studied. Using an approach based on intr…

Collective excitations of a two-dimensional interacting Bose gas in anti-trap and linear external potentials
D. V. Fil, S. I. Shevchenko
We present a method of finding approximate analytical solutions for the spectra and eigenvectors of collective modes in a two-dimensional system of interacting bosons subjected to…
