The anomalous tunneling of Bose-condensate excitations
Yu. Kagan, D. L. Kovrizhin, L. A. Maksimov
We discuss the tunneling of phonon excitations across a potential barrier separating two condensate bulks. It is shown that the strong barrier proves to be transparent for the exci…

"Cherenkov radiation" of a sound in a Bose-condensed gas
D. L. Kovrizhin, L. A. Maksimov
In terms of linearized Gross-Pitaevskii equation we have studied the process of sound emission arises from a supersonic particle motion in a Bose-condensed gas. By analogy with the…

Exact form of the Bogoliubov excitations in one-dimensional nonlinear Schrödinger equation
D. L. Kovrizhin
In the paper we present the exact solutions of one-dimensional Nonlinear Schrödinger Equation. The solutions correspond to the Bogoliubov excitations in Bose-gas with a local inter…
