Enhanced sensing mechanism based on shifting an exceptional point
Xuan Mao, Guo-Qing Qin, Hao Zhang +4
Non-Hermitian systems associated with exceptional points (EPs) are expected to demonstrate a giant response enhancement for various sensors. The widely investigated enhancement mec…
Proximity-encirclement of exceptional points in a multimode optomechanical system
Zheng Fan, Dan Long, Xuan Mao +4
Dynamic encircling a second-order exception point (EP) exhibit chiral state transfer, while there is few research on dynamic encircling multiple and higher-order EPs. Here, we stud…
Optomechanical compensatory cooling mechanism with exceptional points
Guo-Qing Qin, Xuan Mao, Hao Zhang +4
The ground state cooling of Brillouin scattering optomechanical system is limited by defects in practical sample. In this paper, we propose a new compensatory cooling mechanism for…
Simultaneous ground-state cooling of multiple degenerate mechanical modes through cross-Kerr effect
Pengyu Wen, Xuan Mao, Min Wang +3
Simultaneous ground-state cooling of multiple degenerate mechanical modes is a tough issue in optomechanical system due to the existence of the dark mode effect. Here we propose a…
Dynamical encircling exceptional point in largely detuned multimode optomechanical system
Dan Long, Xuan Mao, Guo-Qing Qin +4
Dynamical encircling exceptional point(EP) shows a number of intriguing physical phenomena and its potential applications. To enrich the manipulations of optical systems in experim…
Optomechanically induced transparency and directional amplification in a non-Hermitian optomechanical lattice
Pengyu Wen, Min Wang, Gui-Lu Long
Cavity optomechanics is important in both quantum information processing and basic physics research. In this paper, we propose an optomechanical lattice which manifests non-Hermiti…
