Generation and decay of persistent current in a toroidal Bose-Einstein condensate
A. I. Yakimenko, S. I. Vilchinskii, Y. M. Bidasyuk +3
Persistent current, or "flow without friction", as well as quantum vortices are the hallmarks of superfluidity. Recently a very long-lived persistent flow of atoms has been experim…
Vortices in a toroidal Bose-Einstein condensate with a rotating weak link
A. I. Yakimenko, Y. M. Bidasyuk, M. Weyrauch +2
Motivated by a recent experiment [K.C. Wright et. al. Phys. Rev. Lett. 110, 025302 (2013)], we investigate deterministic discontinuous jumps between quantized circulation states in…
Vortex excitation in a stirred toroidal Bose-Einstein condensate
A. I. Yakimenko, K. O. Isaieva, S. I. Vilchinskii +1
Motivated by the recent experiment [Wright et al., Phys. Rev. A 88, 063633 (2013)], we investigate formation of vortices in an annular BEC stirred by a narrow blue-detuned optical…
Post-inflationary preheating with weak coupling
Igor Rudenok, Yuri Shtanov, Stanislav Vilchinskii
Particle production in the background of an external classical oscillating field is a key process describing the stage of preheating after inflation. For sufficiently strong coupli…
