Realizations of non-linear quantum maps in the one-atom maser model — •Felix Weber, Zsolt Bernád, and Gernot Alber — Institut für Angewandte Physik, Tenchnische Universität Darmstadt, D-64289 Darmstadt

We investigate the iterative behavior of a single mode cavity field which interacts repeatedly with two-level atoms. In our scenario two-level atoms are successively inserted into the cavity containing a superposition of Fock states and interact with this field. Subsequently, the atoms leaving the cavity are postselected. We study the behavior of the photonic state resulting from many iterations of this postselection process. For arbitrary initial conditions and interaction times the fixed points of this transformation and the state to which the field converges after many iterations are determined.
