High precision solutions to quantized vortices within Gross-Pitaevskii equation
Hao-Hao Peng, Jian Deng, Sen-Yue Lou +1
The dynamics of vortices in Bose-Einstein condensates of dilute cold atoms can be well formulated by Gross-Pitaevskii equation. To better understand the properties of vortices, a s…

A topological realization of spin polarization through vortex formation in collisions of Bose-Einstein condensates
Jian Deng, Qun Wang, Hong Zhang
The global spin polarization of hadrons in heavy ion collisions has been measured in STAR (the Solenoidal Tracker At Relativistic heavy ion collider) experiments, which opens up a…

Anharmonicity-Induced Criticality of Collective Excitation in a Trapped Bose-Einstein Condensate
Qun Wang, Bo Xiong
We investigate the low energy excitations of a dilute atomic Bose gas confined in a anharmonic trap interacting with repulsive forces. The dispersion law of both surface and compre…
