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…

Ultrafast Electron Cooling in an Expanding Ultracold Plasma
Tobias Kroker, Mario Großmann, Klaus Sengstock +3
Plasma dynamics critically depends on density and temperature, thus well-controlled experimental realizations are essential benchmarks for theoretical models. The formation of an u…
