We study behavior disordered potential realm Bogoliubov-Huang-Meng theory. Corrections due to quantum fluctuations, effects relative motion fluids fraction, condensed depletion, anomalous equation state each species are obtained analytically for velocity. show that intriguing interplay could not only change stability condition, but destroy also localization process condensates preventing formation Bose glass state. Unexpectedly, we find reduce with The theoretical predictions checked by our numerical results.

Stratification of Moving Multicomponent Bose-Einstein Condensates

A mixture of the multicomponent Bose-Einstein condensate is considered, where each component moves with its own velocity. As a result of the relative motion, the mixture stratifies when the relative velocity reaches a critical value. Stability conditions for a binary moving mixture are derived and the critical velocity is found.

Structure of binary Bose-Einstein condensates

We identify all possible classes of solutions for two-component Bose-Einstein condensates (BECs) within the Thomas-Fermi (TF) approximation, and check these results against numerical simulations of the coupled Gross-Pitaevskii equations (GPEs). We find that they can be divided into two general categories. The first class contains solutions with a region of overlap between the components. The ot...

Adiabaticity criterion for moving vortices in dilute Bose-Einstein condensates.

Considering a moving vortex line in a dilute atomic Bose-Einstein condensate within time-dependent Hartree-Fock-Bogoliubov-Popov theory, we derive a criterion for the quasiparticle excitations to follow the vortex core rigidly. The assumption of adiabaticity, which is crucial for the validity of the stationary self-consistent theories in describing such time-dependent phenomena, is shown to imp...

Vortex excitations in binary mixture of trapped Bose-Einstein condensates

Elementary excitations of vortices placed in one component of a binary mixture of Bose-Einstein condensates have been studied using perturbative and numerical solutions of the linearised equations for excitations, and numerical simulation of the coupled Gross-Pitaevskii equations. Two distinct instabilities originating from resonances of the excitations have been found. One leads to the vortex ...
