Topological Quantum Phase Transition and Local Topological Order in a Strongly Interacting Light-Matter System

Abstract An attempt is made to understand the topological quantum phase transition, emergence of relativistic modes and local topological order of light in a strongly interacting light-matter system. We study this system, in a one dimensional array of nonlinear cavities. Topological quantum phase tr...
