The stationary solutions of G-P equations in double square well
Weidong Li
We present analytical stationary solutions for the Gross-Pitaevskii equation (GPE) of a Bose-Einstein condensate (BECs) trapped in a double-well potential. These solutions are comp…
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…
Density distributions for trapped one-dimensional spinor gases
Yajiang Hao, Yunbo Zhang, J. Q. Liang +1
We numerically evaluate the density distribution of a spin-1 bosonic condensate in its ground state within a modifed Gross-Pitaevskii theory, which is obtained by the combination o…
Entanglement characteristics of subharmonic modes reflected from cavity for type II second harmonic generation
Zehui Zhai, Yongming Li, Jiangrui Gao
Quantum fluctuation and quantum entanglement of the pump field reflected from an optical cavity for type II second harmonic generation are theoretically analyzed. The correlation s…
