Transition to Instability in a Periodically Kicked Bose-Einstein Condensate on a Ring
Jie Liu, Chuanwei Zhang, Mark G. Raizen +1
A periodically kicked ring of a Bose-Einstein condensate is considered as a nonlinear generalization of the quantum kicked rotor, where the nonlinearity stems from the mean field i…
Berry Phase Effects on Dynamics of Quasiparticles in a Superfluid with a Vortex
Chuanwei Zhang, Artem M. Dudarev, Qian Niu
We study quasiparticle dynamics in a Bose-Einstein condensate with a vortex by following the center of mass motion of a Bogoliubov wavepacket, and find important Berry phase effect…
Fidelity of a Bose-Einstein Condensate
Jie Liu, Wenge Wang, Chuanwei Zhang +2
We investigate fidelity, the Loschmidt echo, for a Bose-Einstein Condensate. It is found that the fidelity decays with time in various ways (exponential, Gaussian, and power-law),…
