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…
Experimental demonstration of phase-matching and Sagnac effect in a millimeter-scale wedged resonator gyroscope
Xuan Mao, Hong Yang, Dan Long +7
The highly efficient coupling of light from conventional optical components to optical mode volumes lies in the heart of chip-based micro-devices, which is determined by the phase-…
