Photon Squeezing and Its Signatures of Quantum Phase Transitions in the Open Quantum Rabi-Stark Model
Tian Ye, Xinghan Chen, Chen Wang
As a hallmark of nonclassical light, squeezed light is of profound theoretical interest and holds broad practical promise for emerging quantum technologies. In this work, we invest…

Superradiant phase transitions in the quantum Rabi model: Overcoming the no-go theorem through anisotropy
Tian Ye, Yan-Zhi Wang, Xiang-You Chen +2
Although the superradiant phase transition (SRPT) is prohibited in the paradigmatic quantum Rabi model due to the no-go theorem caused by the term, we demonstrate tw…

Controlling Symmetries and Quantum Criticality in the Anisotropic Coupled-Top Model
Wen-Jian Mao, Tian Ye, Liwei Duan +1
We investigate the anisotropic coupled-top model, which describes the interactions between two large spins along both and directions. By tuning anisotropic coupling streng…
