Trapping states of the electromagnetic field. — •Melanie Rolles, Christian Arenz, and Giovanna Morigi — Universität des Saarlandes

The dynamics of the electromagnetic field of a high-finesse resonator, which is pumped by a beam of "two-level" atoms, can exhibit trapping states when the strong coupling regime holds [1,2]. Trapping states are fixed points of the dynamics, which occur for well defined interaction times, and can exhibit marked non-classical features [2,3]. In this work we study the existence of trapping states of two-modes of a high-finesse microwave resonator, which are pumped by a beam of multilevel atoms. In particular, we analyze the conditions on the atomic configurations, on the coupling and on the interaction times which can lead to the creation of stable, entangled states of the cavity field modes.
