Fate and origin of the quantum Otto heat engine based on the dissipative Dicke-Hubbard model
He-Guang Xu, Shujie Cheng
The Dicke-Hubbard model, describing an ensemble of interacting atoms in a cavity, provides a rich platform for exploring collective quantum phenomena. However, its potential for qu…

Exploring Metallic-Insulating Transition and Thermodynamic Applications of Fibonacci Quasicrystals
He-Guang Xu, Shujie Cheng
Extended and critical states are two common phenomena in Fibonacci quasicrystals. In this paper, we first reveal the difference between the extended phase and the critical phase in…

Two-photon statistics of nonclassical radiation in the dissipative finite-size Dicke model
Heguang Xu, Chen Wang, Xianlong Gao
The nonclassical feature of photons in the open finite-size Dicke model is investigated via the two-photon correlation function. The quantum dressed master equation combined with t…
