Critical Phenomena in Light–Matter Systems with Collective Matter Interactions

Critical Phenomena in Light–Matter Systems with Collective Matter Interactions

We study the quantum phase diagram and the onset of quantum critical phenomena in a generalized Dicke model that includes collective qubit–qubit interactions. By employing semiclassical techniques, we analyze the corresponding classical energy surfaces, fixed points, and the smooth Density of States...
