Hybridized Frequency Combs in Multimode Cavity Electromechanical System
Sishi Wu, Yulong Liu, Qichun Liu +3
The cavity electromechanical devices with radiation-pressure-interaction induced Kerr-like nonlinearity are promising candidates to generate microwave frequency combs. We construct…
Energy-level-attraction and heating-resistant-cooling of mechanical resonators with exceptional points
Cheng Jiang, Yu-Long Liu, Mika A. Sillanpää
We study the energy-level evolution and ground-state cooling of mechanical resonators under a synthetic phononic gauge field. The tunable gauge phase is mediated by the phase diffe…
Observation of anti-PT symmetry phase transition in the magnon-cavity-magnon coupled system
Jie Zhao, Yulong Liu, Longhao Wu +3
As the counterpart of PT symmetry, abundant phenomena and potential applications of anti-PT symmetry have been predicted or demonstrated theoretically. However, experimental realiz…
Mechanically modulated emission spectra and blockade of polaritons
Sai-Nan Huai, Yu-Long Liu, Yunbo Zhang +1
We study a hybrid semiconductor-optomechanical system, which consists of a cavity with an oscillating mirror made by semiconducting materials or with a semiconducting membrane insi…
