Continuous measurements enhanced self-trapping of degenerate ultra-cold atoms: Nonlinear Quantum Zeno Effect
WeiDong Li, Jie Liu
In the present paper we investigate the influence of measurements on the quantum dynamics of degenerate Bose atoms gases in a symmetric double-well. We show that continuous measure…
Commutability between Semiclassical Limit and Adiabatic Limit
Biao Wu, Jie Liu
We study the semiclassical limit and the adiabatic limit with a second-quantized two-mode model, which describes a many-boson interacting system. When its mean-field interaction is…
Quantum Chaos of Bogoliubov Waves for a Bose-Einstein Condensate in Stadium Billiards
Chuanwei Zhang, Jie Liu, Mark G. Raizen +1
We investigate the possibility of quantum (or wave) chaos for the Bogoliubov excitations of a Bose-Einstein condensate in billiards. Because of the mean field interaction in the co…
Adiabatic Geometric Phase for a General Quantum States
Biao Wu, Jie Liu, Qian Niu
A geometric phase is found for a general quantum state that undergoes adiabatic evolution. For the case of eigenstates, it reduces to the original Berry's phase. Such a phase is ap…
Critical onset in coherent oscillations between two weakly coupled Bose-Einstein condensates
Li-Bin Fu, Jie Liu, Shi-Gang Chen
The Josephson effects in two weakly linked Bose-Einstein condensates have been studied recently. In this letter, we study the equations derived by Giovanazzi et. al. [Phys. Rev. Le…
Adiabatic Theory of Nonlinear Evolution of Quantum States
Jie Liu, Biao Wu, Qian Niu
We present a general theory for adiabatic evolution of quantum states as governed by the nonlinear Schrodinger equation, and provide examples of applications with a nonlinear tunne…
