Rev. Lett. 96, 065702 (2006)] predicts glassy behaviour of light in a nonlinear random medium. This implies slow dynamics related to the presence of many metastable states. We consider very general equations (that also apply to other systems, like Bose-Condensed gases) describing light in a disordered non-linear medium and through some approximations we relate them to a mean-field spin-glass-like model. The model is solved by the replica method, and replica-symmetry breaking phase transition is predicted. The transition describes a mode-locking process in which the phases of the modes are locked to random (history and sample-dependent) values. The results are based on very general theory, and embrace a variety of physical phenomena.", "revisions": [ { "version": "v2", "updated": "2006-09-12T16:43:42.000Z" } ], "analyses": { "keywords": [ "random lasers", "glassy behavior", "replica-symmetry breaking phase transition", "nonlinear random medium", "predicts glassy behaviour" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
