Controlling the superradiant phase transition in the quantum Rabi model
Xuan Xie, Cheng Liu, Lin-Lin Jiang +1
In the ultrastrong-coupling regime, the quantum Rabi model can exhibit quantum phase transition (QPT) when the ratio of the qubit transition frequency to the frequency of the cavit…
Quantum phase transition of the Jaynes-Cummings model
Cheng Liu, Jin-Feng Huang
Herein, we propose an experimentally feasible scheme to show the quantum phase transition of the Jaynes-Cummings (JC) model by modulating the transition frequency of a two-level sy…
Deterministic generation of multi-photon bundles in a quantum Rabi model
Cheng Liu, Jin-Feng Huang, Lin Tian
Multi-photon bundle states are crucial for a broad range of applications such as quantum metrology, quantum lithography, quantum communication, and quantum biology. Here we propose…
Multimode optomechanical cooling via general dark-mode control
Jian Huang, Deng-Gao Lai, Cheng Liu +3
The dark-mode effect is a stubborn obstacle for ground-state cooling of multiple degenerate mechanical modes optomechanically coupled to a common cavity-field mode. Here we propose…
