Production of three-body Efimov molecules in an optical lattice
Martin Stoll, Thorsten Koehler
We study the possibility of associating meta-stable Efimov trimers from three free Bose atoms in a tight trap realised, for instance, via an optical lattice site or a microchip. Th…
Ramsey interferometry with atoms and molecules: two-body versus many-body phenomena
Krzysztof Goral, Thorsten Koehler, Keith Burnett
We discuss the frequency and visibility of atom-molecule Ramsey fringes observed in recent experiments by Claussen et al.[Phys. Rev. A 67, 060701 (2003)]. In these experiments a 85…
Adiabatic association of ultracold molecules via magnetic field tunable interactions
Krzysztof Goral, Thorsten Koehler, Simon A. Gardiner +2
We consider in detail the situation of applying a time dependent external magnetic field to a 87Rb atomic Bose-Einstein condensate held in a harmonic trap, in order to adiabaticall…
Dynamics of correlations in atomic Bose-Einstein condensates
Krzysztof Goral, Thorsten Koehler, Thomas Gasenzer +1
The Gross-Pitaevskii equation has been extremely successful in the theory of weakly-interacting Bose-Einstein condensates. However, present-day experiments reach beyond the regime…
Heating and atom loss during upward ramps of Feshbach resonance levels in Bose-Einstein condensates
Thorsten Koehler, Krzysztof Goral, Thomas Gasenzer
The production of pairs of fast atoms leads to a pronounced loss of atoms during upward ramps of Feshbach resonance levels in dilute Bose-Einstein condensates. We provide comparati…
Diffraction of Weakly Bound Clusters: Spectroscopy and Size Effects
Martin Stoll, Thorsten Koehler, Gerhard C. Hegerfeldt
Exciting experiments in the field of atom and molecule optics have lately drawn much attention to the effects involved in the coherent diffraction of particle beams. We review the…
