Ultrafast many-body dynamics of dense Rydberg gases and ultracold plasma
Mario Großmann, Jette Heyer, Julian Fiedler +4
Understanding Coulomb driven many-body dynamics in ultracold atomic systems far from equilibrium remains an open challenge, particularly when ultrafast excitation channels create c…
Cooling dynamics of a free ion in a Bose-Einstein condensate
Lorenzo Oghittu, Juliette Simonet, Philipp Wessels-Staarmann +4
We investigate the dynamics of an ion moving through a homogeneous Bose-Einstein condensate (BEC) after an initial momentum is imparted. For this, we derive a master equation in th…
Dynamics of Ultracold Quantum Gases in the Dissipative Fermi-Hubbard Model
Koen Sponselee, Lukas Freystatzky, Benjamin Abeln +8
We employ metastable ultracold Yb atoms to study dynamics in the 1D dissipative Fermi-Hubbard model experimentally and theoretically, and observe a complete inhibition of t…
Investigation of Feshbach Resonances in ultra-cold 40 K spin mixtures
Jasper S. Krauser, Jannes Heinze, S. Götze +7
Magnetically-tunable Feshbach resonances are an indispensable tool for experiments with atomic quantum gases. We report on twenty thus far unpublished Feshbach resonances and twent…
Multiphoton interband excitations of quantum gases in driven optical lattices
M. Weinberg, C. Ölschläger, C. Sträter +4
We report on the observation of multiphoton interband absorption processes for quantum gases in shaken light crystals. Periodic inertial forcing, induced by a spatial motion of the…
Engineering spin waves in a high-spin ultracold Fermi gas
Jannes Heinze, Jasper Simon Krauser, Nick Fläschner +5
We report on the detailed study of multi-component spin-waves in an s=3/2 Fermi gas where the high spin leads to novel tensorial degrees of freedom compared to s = 1/2 systems. The…
