Quantum Phase Transitions of Light in the Dicke-Bose-Hubbard model
WebThe phase-change based energy storage provides an excellent solution for the mismatch of energy production and consumption. Cold energy storage tanks filled with PCM balls could be applied in energy-efficient air-conditioning systems. The main advantage lies in the reduction of energy storage space demand compared with water-based cold energy … WebJaynes-Cummings model. With an array of high-Q electromagnetic cavities, each containing a single two-level atom in the photon-blockade regime, quantum phase transitions of photonic insulator (excita-tions localization) to superfluid (excita-tions delocalization) are predicted by the Bose-Hubbard model.2, 3 As the number of TLAs increases, cityheart chester

WebAug 8, 2011 · The Rényi entropies of the Dicke model are presented. This quantum-optical model describes a single-mode bosonic field interacting with an ensemble of N two-level atoms. There is a quantum phase transition in the N → ∞ limit. It is shown that there is an abrupt change in the Rényi entropy of order β at the transition point. Around the critical … WebJun 12, 2003 · We investigate the quantum-chaotic properties of the Dicke Hamiltonian; a quantum-optical model that describes a single-mode bosonic field interacting with an ensemble of N two-level atoms. This model exhibits a zero-temperature quantum phase transition in the N → ∞ limit, which we describe exactly in an effective Hamiltonian … WebNov 30, 2024 · The Dicke model, which describes the coupling of an ensemble of spins to a harmonic oscillator, is known for its superradiant phase transition, which can both be observed in the ground state in a purely Hamiltonian setting, as well as in the steady state of an open-system Dicke model with dissipation. We demonstrate that, in addition, the … did bank of canada raise rates today
