Stationary non-classical states of a two mode cavity — •Christian Arenz1,2, Melanie Rolles1,3, and Giovanna Morigi1 — 1Saarland University — 2Aberystwyth University — 3University of Luxembourg
The dynamics of the electromagnetic field of a high-finesse resonator is studied, when it interacts with individual atoms of a beam [1]. These dynamics are well modeled by a Jaynes-Cummings type of Hamiltonian. In the strong coupling regime it was shown that trapping states of one field mode can be observed for well defined interaction times [2,3]. Depending on the initial state of the atoms this leads to asymptotic states of the cavity field dynamics that have non-classical features [4].
In this work we consider the energy levels of the atoms in a V-type configuration, where the dipoles are resonantly coupled to two field modes. We show that for well defined interaction times a trapping condition similar to the one mode case can be defined. We determine the asymptotic state of the field dynamics if the atoms that are injected into the cavity are prepared in a coherent superposition of their excited levels. We show that the asymptotic state is a pure entangled state and characterize its properties.
