Quantum reflection of a Bose-Einstein condensate from a rapidly varying potential: the role of dark soliton
Dongmei Wang, Bo Xiong, Tao Yang
We study the dynamic behavior of a Bose-Einstein condensate (BEC) containing a dark soliton separately reflected from potential drops and potential barriers. It is shown that for a…
Turbulent cascade induced persistent current of cold atomic superfluids
Xiyu Chen, Tao Yang, Wen-Li Yang +1
Dissipating of disorder quantum vortices in an annular two-dimensional Bose-Einstein condensate can form a macroscopic persistent flow of atoms. We propose a protocol to create per…
Topological transition from superuid vortex rings to isolated knots and links
Wen-Kai Bai, Tao Yang, Wu-Ming Liu
Knots and links are fundamental topological objects play a key role in both classical and quantum fluids. In this research, we propose a novel scheme to generate torus vortex knots…
Controllable splitting dynamics of a doubly quantized vortex in a rotating ring-shaped condensate
Bo Xiong, Tao Yang, Yu-Ju Lin +1
We study the dynamics of a doubly quantized vortex (DQV), created by releasing a ring-shaped Bose-Einstein condensate with quantized circulation into harmonic potential traps. It i…
Influence of a dark-soliton on the reflection of a Bose-Einstein condensate by a square barrier
Qiao-Ling Cheng, Wen-Kai Bai, Yao-Zhong Zhang +2
We study the quantum reflection of a two-dimensional disk-shaped Bose-Einstein condensate with a dark-soliton excitation by a square potential barrier. For the giving geometry, the…
Dynamics of vortex quadrupoles in nonrotating trapped Bose-Einstein condensate
Tao Yang, Zhi-Qiang Hu, Shan Zou +1
Dynamics of vortex clusters is essential for understanding diverse superfluid phenomena. In this paper, we examine the dynamics of vortex quadrupoles in a trapped two-dimensional (…
