Solution of the Riemann problem for polarization waves in a two-component Bose-Einstein condensate
S. K. Ivanov, A. M. Kamchatnov, T. Congy +1
We provide a classification of the possible flow of two-component Bose-Einstein condensates evolving from initially discontinuous profiles. We consider the situation where the dyna…

Composite boson description of a low density gas of excitons
A. E. Golomedov, Yu. E. Lozovik, G. E. Astrakharchik +1
Ground state properties of a fermionic Coulomb gas are calculated using the fixed-node diffusion Monte Carlo method. The validity of the composite boson description is tested for d…

Expansion Dynamics of a Two-Component Quasi-One-Dimensional Bose-Einstein Condensate: Phase Diagram, Self-Similar Solutions, and Dispersive Shock Waves
S. K. Ivanov, A. M. Kamchatnov
We investigate the expansion dynamics of a Bose-Einstein condensate that consists of two components and is initially confined in a quasi-one-dimensional trap. We classify the possi…
