Thermal spin fluctuations in spinor Bose-Einstein condensates
Marina Melé-Messeguer, Bruno Juliá-Díaz, Artur Polls +1
We study the thermal activation of spin fluctuations in dynamically-stable spinor Bose-Einstein condensates. We analyze the specific cases of a non-dipolar spin-1 condensate in m =…
Quasihole dynamics as a detection tool for quantum Hall phases
Tobias Graß, Bruno Juliá-Díaz, Maciej Lewenstein
Existing techniques for synthesizing gauge fields are able to bring a two-dimensional cloud of harmonically trapped bosonic atoms into a regime where the occupied single-particle s…
Spin-driven spatial symmetry breaking of spinor condensates in a double-well
Marina Melé-Messeguer, Simone Paganelli, Bruno Juliá-Díaz +2
The properties of an F=1 spinor Bose-Einstein condensate trapped in a double-well potential are discussed using both a mean-field two-mode approach and a simplified two-site Bose-H…
Fast generation of spin-squeezed states in bosonic Josephson junctions
B. Juliá-Díaz, E. Torrontegui, J. Martorell +2
We describe methods for fast production of highly coherent-spin-squeezed many-body states in bosonic Josephson junctions (BJJs). We start from the known mapping of the two-site Bos…
Beyond standard two-mode dynamics in Bosonic Josephson junctions
B. Juliá-Díaz, J. Martorell, M. Melé-Messeguer +1
We examine the dynamics of a Bose-Einstein condensate in a symmetric double-well potential for a broad range of non-linear couplings. We demonstrate the existence of a region, beyo…
