Finite-system Multicriticality at the Superradiant Quantum Phase Transition
Han-Jie Zhu, Kai Xu, Guo-Feng Zhang +1
We demonstrate the existence of finite-system multicriticality in a qubit-boson model where biased qubits collectively coupled to a single-mode bosonic field. The interplay between…
Detecting the entanglement of vortices in ultracold bosons with artificial gauge fields
Li Dai, Lin Xia, Lin Zhuang +1
The entanglement of vortices in a two-dimensional Bose-Hubbard model with artificial gauge fields is investigated using the exact diagonalization techniques. We propose an effectiv…
Dynamical Phase Transition of two-component Bose-Einstein condensate with nonlinear tunneling in an optomechanical cavity-mediated double-well system
Qing Li, Lei Tan, Jin-Lou Ma +3
We investigate the dynamical phase transition of two-component Bose-Einstein condensate with nonlinear tunneling, which is trapped inside a double-well and dispersively coupled to…
The effect of oscillator and dipole-dipole interaction on multiple optomechanically induced transparency in cavity optomechanical system
Jin-Lou Ma, Lei Tan, Qing Li +2
We theoretically investigate the optomechanically induced transparency (OMIT) phenomenon in a N-cavity optomechanical system doped with a pair of Rydberg atoms with the presence of…
Auxiliary-cavity-assisted ground-state cooling of optically levitated nanosphere in the unresolved-sideband regime
Jin-Shan Feng, Lei Tan, Huai-Qiang Gu +1
We theoretically analyse the ground-state cooling of optically levitated nanosphere in unresolved- sideband regime by introducing a coupled high-quality-factor cavity. On account o…
Quantum phase transitions of light in a dissipative Dicke-Bose-Hubbard model
Ren-Cun Wu, Lei Tan, Wen-Xuan Zhang +1
The impacts that the environment has on the quantum phase transition of light in the DickeBose-Hubbard model are investigated. Based on the quasibosonic approach, mean field theory…
