The Dicke Model is a theoretical framework in quantum physics that describes a system of multiple two-level atoms interacting with a single mode of electromagnetic radiation. It was introduced by physicist Robert Dicke in 1954 to explain collective phenomena in atomic systems, such as superradiance, where atoms emit light more intensely when they are in a collective state. In the Dicke Model, the atoms are coupled to a cavity field, allowing for the exchange of energy between the atoms and the field. This model has applications in various fields, including quantum optics and condensed matter physics, and helps in understanding phenomena like phase transitions and quantum coherence in many-body systems.
