Dicke Quantum Spin Glass of Atoms and Photons
Dicke Quantum Spin Glass of Atoms and Photons
Recent studies of strongly interacting atoms and photons in optical cavities have rekindled interest in the Dicke model of atomic qubits coupled to discrete photon cavity modes. We study the multimode Dicke model with variable atom-photon couplings. We argue that a quantum spin glass phase can appear, with a random …
