Disorder-Induced Phase Control in Superfluid Fermi-Bose Mixtures
Armand Niederberger, Jan Wehr, Maciej Lewenstein +1
We consider a mixture of a superfluid Fermi gas of ultracold atoms and a Bose-Einstein condensate of molecules possessing a continuous U(1) (relative phase) symmetry. We study the…
Quantum phase transition and critical fluctuations of an attractive Bose gas in a double well potential
P. Ziń, J. Chwedeńczuk, B. Oleś +2
We consider a Bose gas with an attractive interaction in a symmetric double well potential. In the Hartree approximation, the ground state solution spontaneously breaks the symmetr…
Disorder-Induced Order in Two-Component Bose-Einstein Condensates
Armand Niederberger, Thomas Schulte, Jan Wehr +3
We propose and analyze a general mechanism of disorder-induced order in two-component Bose-Einstein condensates, analogous to corresponding effects established for XY spin models.…
Routes towards Anderson-Like localization of Bose-Einstein condensates in disordered optical lattices
T. Schulte, S. Drenkelforth, J. Kruse +5
We investigate, both experimentally and theoretically, possible routes towards Anderson-like localization of Bose-Einstein condensates in disordered potentials. The dependence of t…
Mean field loops versus quantum anti-crossing nets in trapped Bose-Einstein condensates
Zbyszek P. Karkuszewski, Krzysztof Sacha, Augusto Smerzi
We study a Bose-Einstein condensate trapped in an asymmetric double well potential. Solutions of the time-independent Gross-Pitaevskii equation reveal intrinsic loops in the energy…
