Modelling many-body Rydberg interactions — •David Schönleber, Martin Gärttner, and Jörg Evers — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg

In the field of Rydberg physics, basically two approaches to modelling many-body interactions exist, namely the approach to solve the many-body Schrödinger equation and the approach to solve effective models such as rate equations. While the first approach includes exact correlation effects which the latter neglects, it does not include reservoir effects such as damping. We develop methods to augment the exact many-body Hamiltonian approach with the ability to model reservoir effects e.g. by implementing quantum jumps via Monte Carlo techniques [1], aiming to enlarge the field of validity of the Schrödinger equation approach. Consequently, the scope of the methods developed is studied with respect to the conventional models.
