Quasi-one-dimensional flow of polariton condensate past an obstacle
Anatoly M. Kamchatnov, Yaroslav V. Kartashov
Nonlinear wave patterns generated by the flow of polariton condensate past an obstacle are studied for quasi-one-dimensional microcavity geometry. It is shown that pumping and nonl…
Oblique solitons in the flow of polariton condensate past an obstacle
A. M. Kamchatnov, S. V. Korneev
Formation of oblique solitons by a flow of polariton condensate past an obstacle is considered. The flow is non-uniform due to a finite life-time of polaritons what changes drastic…
Generation of dispersive shock waves by the flow of a Bose-Einstein condensate past a narrow obstacle
A. M. Kamchatnov, N. Pavloff
We study the flow of a quasi-one-dimensional Bose-Einstein condensate incident onto a narrow obstacle. We consider a configuration in which a dispersive shock is formed and propaga…
Phase diagram of Rydberg atoms with repulsive van der Waals interaction
O. N. Osychenko, G. E. Astrakharchik, Y. Lutsyshyn +2
We report a quantum Monte Carlo calculation of the phase diagram of bosons interacting with a repulsive inverse sixth power pair potential, a model for assemblies of Rydberg atoms…
Mesoscopic supersolid of dipoles in a trap
A. E. Golomedov, G. E. Astrakharchik, Yu. E. Lozovik
A mesoscopic system of indirect dipolar bosons trapped by a harmonic potential is considered. The system has a number of physical realizations including dipole excitons, atoms with…
Condition for convective instability of dark solitons
A. M. Kamchatnov, S. V. Korneev
Simple derivation of the condition for the transition point from absolute instability of plane dark solitons to their convective instability is suggested. It is shown that unstable…
