Dissipative Quantum State Engineering with Atoms and Molecules — •Hendrik Weimer — Institut für Theoretische Physik, Leibniz Universität Hannover, Germany

While dissipation is generally thought to be an undesirable process for the observation of coherent dynamics, it is actually possible to turn controlled dissipation into a useful resource for the realization of strongly correlated quantum states. In this context, I will discuss the possibility for a novel dissipatively bound state between ultracold atoms or molecules [1], as well as recent results on the dissipative preparation of topologically ordered many-body states using polar molecules [2]. Finally, I will present a new mechanism for the quantum simulation of extended Hubbard models using Rydberg atoms [3].
