Spinor self-ordering of thermal atoms in an optical cavity — •Luigi Giannelli, Simon Jäger, and Giovanna Morigi — Theoretische Physik, Universität des Saarlandes, 66123 Saarbrücken, Germany

We theoretically analyze the dynamics of cold atomic spins in a single-mode standing-wave cavity as a function of the intensity and relative phase of two transverse lasers, driving the atoms. We identify and discuss the conditions under which stable spatial patterns form, where atomic position and spin phase are correlated. We analyze spin-motion correlations and their dynamics. We finally analyze the properties of the light emitted by the cavity as a method to reveal the state of the system.
