My group investigates long-range interactions between atoms in the gas phase. To this end we cool atomic gases down to temperature of a few mikrokelvin and then bring them by laser excitation into a highly-excited electronic state (Rydberg atom). In this state, the atoms start to interact strongly with other atoms and their environment. We study exotic molecular binding mechanisms arising from these interactions and the complex many-body dynamics of out-of-equilibrium systems.
