Nonlinear semiclassical dynamics of the unbalanced, open Dicke model
WebThe Dicke model, which describes a quantized light field interacting with an ensemble of two-level atoms, is a cornerstone model of quantum optics. It illustrates the collective phenomena of superradiance in a non-transient way through the second-order superradiant phase transition observed when the light-atom interaction strength is varied. WebThe Dicke model describes the coupling between a quantized cavity field and a large ensemble of two-level atoms. When the number of atoms tends to infinity, this model can … chilton manual jeep wrangler
