Molecular production in two-component atomic Fermi gases
Jan Chwedenczuk, Krzysztof Goral, Thorsten Koehler +1
We provide a practical approach to the molecular production via linear downward sweeps of Feshbach resonances in degenerate Fermi gases containing incoherent mixtures of two atomic…
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…
Hydrodynamic excitations of trapped dipolar fermions
K. Goral, M. Brewczyk, K. Rzazewski
A single-component Fermi gas of polarized dipolar particles in a harmonic trap can undergo a mechanical collapse due to the attractive part of the dipole-dipole interaction. This p…
