Ground State Properties of Cold Bosonic Atoms At Large Scattering Lengths
Jun Liang Song, Fei Zhou
In this letter, we study bosonic atoms at large scattering lengths using a variational method where the condensation amplitude is a variational parameter. We further examine moment…
Quantum-Fluctuation-Driven Coherent Spin Dynamics in Small Condensates
Xiaoling Cui, Yupeng Wang, Fei Zhou
We have studied quantum spin dynamics of small condensates of cold sodium atoms. For a condensate initially prepared in a mean field ground state, we show that coherent spin dynami…
Dynamical Creation of Fractionalized Vortices and Vortex Lattices
An-Chun Ji, W. M. Liu, Jun Liang Song +1
We investigate dynamic creation of fractionalized half-quantum vortices in Bose-Einstein condensates of sodium atoms. Our simulations show that both individual half-quantum vortice…
Tunable Quantum Fluctuation-Controlled Coherent Spin Dynamics
Jun Liang Song, Fei Zhou
Temporal evolution of a macroscopic condensate of ultra cold atoms is usually driven by mean field potentials, either due to scattering between atoms or due to coupling to external…
Discrete symmetries and 1/3-quantum vortices in condensates of F=2 cold atoms
Gordon W. Semenoff, Fei Zhou
In this Letter we study discrete symmetries of mean field manifolds of condensates of F=2 cold atoms, and various unconventional quantum vortices. Discrete quaternion symmetries re…
