Quantum phase transitions and critical behaviors in the two-mode three-level quantum Rabi model
Yan Zhang, Bin-Bin Mao, Dazhi Xu +4
We explore an extended quantum Rabi model describing the interaction between a two-mode bosonic field and a three-level atom. Quantum phase transitions of this few degree of freedo…
Variational study of two-impurity spin-boson model with a common Ohmic bath: Ground-state phase transitions
Nengji Zhou, Yuyu Zhang, Zhiguo Lu +1
By means of a trial wave function, the multi-D ansatz, extensive variational calculations with more than ten thousand parameters have been carried out to study quantum phase tr…
Charging of quantum batteries with general harmonic power
Jie Chen, Liyao Zhan, Lei Shao +3
We analyse the charging process of quantum batteries with general harmonic power. To describe the charge efficiency, we introduce the charge saturation and the charging power, and…
Dissipative dynamics in a tunable Rabi dimer with periodic harmonic driving
Zhongkai Huang, Fulu Zheng, Yuyu Zhang +2
Recent progress on qubit manipulation allows application of periodic driving signals on qubits. In this study, a harmonic driving field is added to a Rabi dimer to engineer photon…
Generalized coherent-squeezed-state expansion for the quantum Rabi model
Xiang-You Chen, Yu-Yu Zhang, Hang Zheng
We develop a systematic variational coherent-squeezed-state expansion for the ground state of the quantum Rabi model, which includes an additional squeezing effect with comparisons…
