Properties of strongly dipolar Bose gases beyond the Born approximation
Rafał Ołdziejewski, Krzysztof Jachymski
Strongly dipolar Bose gases can form liquid droplets stabilized by quantum fluctuations. In theoretical description of this phenomenon, low energy scattering amplitude is utilized…
Inelastic collisions of ultracold triplet Rb molecules in the rovibrational ground state
Björn Drews, Markus Deiß, Krzysztof Jachymski +2
Exploring inelastic and reactive collisions on the quantum level is a main goal of the developing field of ultracold chemistry. We present first experimental studies of inelastic c…
Importance of rotationally inelastic processes in low-energy Penning ionization of CHF
Justin Jankunas, Krzysztof Jachymski, Michał Hapka +1
Low energy reaction dynamics can strongly depend on the internal structure of the reactants. The role of rotationally inelastic processes in cold collisions involving polyatomic mo…
Three-body interaction of Rydberg slow light polaritons
Krzysztof Jachymski, Przemysław Bienias, Hans Peter Büchler
We study a system of three photons in an atomic medium coupled to Rydberg states near the conditions of electromagnetically induced transparency. Based on the analytical analysis o…
Impact of overlapping resonances on magnetoassociation of cold molecules in tight traps
Krzysztof Jachymski
Overlapping Feshbach resonances are commonly observed in experiments with ultracold atoms and can influence the molecule production process. We derive an effective approach to desc…
