Exploring the role of criticality in the quantum Otto cycle fueled by the anisotropic quantum Rabi-Stark model
He-Guang Xu, Jiasen Jin, Norton G. de Almeida +1
Quantum heat machines, encompassing heat engines, refrigerators, heaters, and accelerators, represent the forefront of quantum thermodynamics, offering a novel paradigm for convert…
Persisting quantum effects in the anisotropic Rabi model at thermal equilibrium
He-Guang Xu, V. Montenegro, Gao Xianlong +2
Quantum correlations and nonclassical states are at the heart of emerging quantum technologies. Efforts to produce long-lived states of such quantum resources are a subject of tire…
Universal quantum Otto heat machine based on the Dicke model
He-Guang Xu, Jiasen Jin, G. D. M. Neto +1
In this paper we study a quantum Otto thermal machine where the working substance is composed of N identical qubits coupled to a single mode of a bosonic field, where the atoms and…
Quantum criticality driven by the cavity coupling in Rabi-dimer model
Shujie Cheng, Heguang Xu, Xueying Liu +1
The superradiant phase transition (SPT) controlled by the interacting strength between the two-level atom and the photons has been a hot topic in the Rabi model and the Rabi-dimer…
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…
