Self-Trapping of Bosons and Fermions in Optical Lattices
Dirk-Sören Lühmann, Kai Bongs, Klaus Sengstock +1
We theoretically investigate the enhanced localization of bosonic atoms by fermionic atoms in three-dimensional optical lattices and find a self-trapping of the bosons for attracti…
Localization and delocalization of ultracold bosonic atoms in finite optical lattices
Dirk-Sören Lühmann, Kai Bongs, Klaus Sengstock +1
We study bosonic atoms in small optical lattices by exact diagonalization and observe a striking similarity to the superfluid to Mott insulator transition in macroscopic systems. T…
Do mixtures of bosonic and fermionic atoms adiabatically heat up in optical lattices?
M. Cramer, S. Ospelkaus, C. Ospelkaus +3
Mixtures of bosonic and fermionic atoms in optical lattices provide a promising arena to study strongly correlated systems. In experiments realizing such mixtures in the quantum de…
Heteronuclear molecules in an optical lattice: Theory and experiment
Frank Deuretzbacher, Kim Plassmeier, Daniela Pfannkuche +5
We study properties of two different atoms at a single optical lattice site at a heteronuclear atomic Feshbach resonance. We calculate the energy spectrum, the efficiency of rf ass…
Dynamics of F=1 87Rb condensates at finite temperatures
Jordi Mur-Petit, Montserrat Guilleumas, Artur Polls +4
We investigate the dynamics of a F=1 spinor Bose-Einstein condensate of 87Rb atoms confined in a quasi-one-dimensional trap both at zero and at finite temperature. At zero temperat…
Interaction-driven Dynamics of 40K / 87Rb Fermi-Bose Gas Mixtures in the Large Particle Number Limit
C. Ospelkaus, S. Ospelkaus, K. Sengstock +1
We have studied effects of interspecies attraction in a Fermi-Bose mixture over a large regime of particle numbers in the 40K / 87Rb system. We report on the observation of a mean…
