Parity-dependent unidirectional and chiral photon transfer in reversed-dissipation cavity optomechanics
Zhen Chen, Qichun Liu, Jingwei Zhou +4
Nonreciprocal elements, such as isolators and circulators, play an important role in classical and quantum information processing. Recently, strong nonreciprocal effects have been…
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…
Optomechanical Anti-lasing with Infinite Group Delay at a Phase Singularity
Yulong Liu, Qichun Liu, Shuaipeng Wang +3
Singularities that symbolize abrupt changes and exhibit extraordinary behavior are of broad interest. We experimentally study optomechanically induced singularities in a compound s…
Parity-symmetry-breaking quantum phase transition via parametric drive in a cavity magnonic system
Guo-Qiang Zhang, Zhen Chen, Wei Xiong +2
We study the parity-symmetry-breaking quantum phase transition (QPT) in a cavity magnonic system driven by a parametric field, where the magnons in a ferrimagnetic yttrium-iron-gar…
Exceptional Point and Cross-Relaxation Effect in a Hybrid Quantum System
Guo-Qiang Zhang, Zhen Chen, Da Xu +7
Exceptional points (EPs) are exotic degeneracies of non-Hermitian systems, where the eigenvalues and the corresponding eigenvectors simultaneously coalesce in parameter space, and…
Photon-Dressed Bloch-Siegert Shift in an Ultrastrongly Coupled Circuit Quantum Electrodynamical System
Shuai-Peng Wang, Guo-Qiang Zhang, Yimin Wang +5
A cavity quantum electrodynamical (QED) system beyond the strong-coupling regime is expected to exhibit intriguing quantum phenomena. Here we report a direct measurement of the pho…
