Excited Thomas-Efimov levels in ultracold gases
Mark D. Lee, Thorsten Koehler, Paul S. Julienne
Since the early days of quantum physics, the complex behavior of three interacting particles has been the subject of numerous experimental and theoretical studies. In a recent Lett…
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…
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…
