Exactness of the mean-field dynamics in optical cavity systems
Takashi Mori
Validity of the mean-field approach to open system dynamics in the optical cavity system is examined. It is rigorously shown that the mean-field approach is justified in the thermo…
Photon and spin dependence of the resonance lines shape in the strong coupling regime
S. Miyashita, T. Shirai, T. Mori +3
We study the quantum dynamics of a spin ensemble coupled to cavity photons. Recently, related experimental results have been reported, showing the existence of the strong coupling…
Equilibrium Properties of Quantum Spin Systems with Non-additive Long-Range Interactions
Takashi Mori
We study equilibrium states of quantum spin systems with non-additive long-range interactions by adopting an appropriate scaling of the interaction strength, i.e., the so called Ka…
Novel symmetry-broken phase in a driven cavity system in the thermodynamic limit
Tatsuhiko Shirai, Takashi Mori, Seiji Miyashita
We study non-equilibrium stationary states of a cavity system consisting of many atoms interacting with a quantized cavity field mode, under a driving field in a dissipative enviro…
