A normalized gradient flow method for computing ground states of spin-2 Bose-Einstein condensates
Weizhu Bao, Qinglin Tang, Yongjun Yuan
We propose and analyze an efficient and accurate numerical method for computing ground states of spin-2 Bose-Einstein condensates (BECs) by using the normalized gradient flow (NGF)…
Hubbard model for atomic impurities bound by the vortex lattice of a rotating BEC
T. H. Johnson, Y. Yuan, W. Bao +3
We investigate cold bosonic impurity atoms trapped in a vortex lattice formed by condensed bosons of another species. We describe the dynamics of the impurities by a bosonic Hubbar…
Breathing oscillations of a trapped impurity in a Bose gas
T. H. Johnson, M. Bruderer, Y. Cai +3
Motivated by a recent experiment [J. Catani et al., arXiv:1106.0828v1 preprint, 2011], we study breathing oscillations in the width of a harmonically trapped impurity interacting w…
Self-trapping of Bose-Einstein condensates expanding into shallow optical lattices
M. Rosenkranz, D. Jaksch, F. Y. Lim +1
We observe a sudden breakdown of the transport of a strongly repulsive Bose-Einstein condensate through a shallow optical lattice of finite width. We are able to attribute this beh…
