Superradiant phase transition induced by the indirect Rabi interaction
Wen Huang, Ying Wu, Xin-You Lü
We theoretically study the superradiant phase transition (SPT) in an indirect Rabi model, where both a two-level system and a single mode bosonic field couple to an auxiliary boson…
Out-of-Time-Order Correlation as a Witness for Topological Phase Transitions
Qian Bin, Liang-Liang Wan, Franco Nori +2
We propose a physical witness for dynamically detecting topological phase transitions (TPTs) via an experimentally observable out-of-time-order correlation (OTOC). The distinguisha…
Squeezed Optomechanics with Phase-matched Amplification and Dissipation
Xin-You Lü, Ying Wu, J. R. Johansson +3
We investigate the nonlinear interaction between a squeezed cavity mode and a mechanical mode in an optomechanical system (OMS) that allows us to selectively obtain either a radiat…
Steady-state Mechanical Squeezing in an Optomechanical System via Duffing Nonlinearity
Xin-You Lü, Jie-Qiao Liao, Lin Tian +1
Quantum squeezing in mechanical systems is not only a key signature of macroscopic quantum effects, but can also be utilized to advance the metrology of weak forces. Here we show t…
