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…
Quantum Physics Exploring Gravity in the Outer Solar System: The Sagas Project
P. Wolf, Ch. J. Bordé, A. Clairon +52
We summarise the scientific and technological aspects of the SAGAS (Search for Anomalous Gravitation using Atomic Sensors) project, submitted to ESA in June 2007 in response to the…
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…
