Spin Self-Organization in an Optical Cavity Facilitated by Inhomogeneous Broadening

Author(s): Marc Nairn, Luigi Giannelli, Giovanna Morigi, Sebastian Slama, Beatriz Olmos, and Simon B. Jäger We study the onset of collective spin self-organization in a thermal ensemble of driven two-level atoms confined in an optical cavity. The atoms spontaneously form a spin pattern above a critical driving strength that sets a threshold and is determined by the cavity parameters, the initial temperatu… [Phys. Rev.
