Exact solution for the inhomogeneous Dicke model in the canonical ensemble: thermodynamical limit and finite-size corrections
W. V. Pogosov, D. S. Shapiro, L. V. Bork +1
We consider an exactly solvable inhomogeneous Dicke model which describes an interaction between a disordered ensemble of two-level systems with single mode boson field. The existi…
Cyclic phase in F=2 spinor condensate: Long-range order, kinks, and roughening transition
W. V. Pogosov, K. Machida
We study the effect of thermal fluctuations on homogeneous infinite Bose-Einstein condensate with spin F=2 in the cyclic state, when atoms occupy three hyperfine states with $m_{F}…
Vortex nucleation in rotating BEC: the role of the boundary condition for the order parameter
W. V. Pogosov, K. Machida
We study the process of vortex nucleation in rotating two-dimensional BEC confined in a harmonic trap. We show that, within the Gross-Pitaevskii theory with the boundary condition…
Thermal fluctuations of vortex clusters in quasi-two-dimensional Bose-Einstein condensate
W. V. Pogosov, K. Machida
We study the thermal fluctuations of vortex positions in small vortex clusters in a harmonically trapped rotating Bose-Einstein condensate. It is shown that the order-disorder tran…
