Formation of a condensed state with macroscopic number of phonons in ultracold Bose gases
Yu. Kagan, L. A. Manakova
A mechanism for the formation of a new type of stationary state with macroscopical number of phonons in condensed atomic gases is proposed. This mechanism is based on generating lo…
Condensation of phonons in an ultracold Bose gas
Yu. Kagan, L. A. Manakova
We consider the generation of longitudinal phonons in an elongated Bose-condensed gas at zero temperature due to parametric resonance as a result of the modulation of the transvers…
Instabilities of one- and two-dimensional degenerate atomic Fermi gas against a long-wave perturbation in optical lattice
L. A. Manakova
A mechanism of both formation of peaks in the density of states near the Fermi surface and phase instabilities of nearly ideal degenerate Fermi gas in low-dimensional optical latti…
Ground State of the Double-Well Condensates Interacting with Trap Oscillations
L. A. Manakova
In the present paper it is shown that the interaction between oscillations of a double-well trappedcondensate and excited Josephson states corresponding to a large enough initial d…
