Multiple atomic dark solitons in cigar-shaped Bose-Einstein condensates
G. Theocharis, A. Weller, J. P. Ronzheimer +4
We consider the stability and dynamics of multiple dark solitons in cigar-shaped Bose-Einstein condensates (BECs). Our study is motivated by the fact that multiple matter-wave dark…
Spatial Dependence of Entropy in Trapped Ultracold Bose Gases
Lincoln D. Carr, Markus K. Oberthaler
We find a new physical regime in the trapped Bose-Hubbard Hamiltonian using time-evolving block decimation. Between Mott-insulating and superfluid phases, the latter induced by tra…
Feynman path-integral treatment of the BEC-impurity polaron
J. Tempere, W. Casteels, M. K. Oberthaler +2
The description of an impurity atom in a Bose-Einstein condensate can be cast in the form of Frohlich's polaron Hamiltonian, where the Bogoliubov excitations play the role of the p…
