Short note on the excitonic Mott phase
K. Ziegler, O. L. Berman, R. Ya. Kezerashvili
An exciton gas on a lattice is analyzed in terms of a convergent hopping expansion. For a given chemical potential our calculation provides a sufficient condition for the hopping r…

Spontaneous formation and non-equilibrium dynamics of a soliton-shaped Bose-Einstein condensate in a trap
Oleg L. Berman, Roman Ya. Kezerashvili, German V. Kolmakov +1
The Bose-stimulated self-organization of a quasi-two dimensional non-equilibrium Bose-Einstein condensate in an in-plane potential is proposed. We obtained the solution of the nonl…
