Quantum Interference Amplifies Weak Chirality into Giant Quantum Nonreciprocity
Jing Tang, Yuangang Deng
Quantum nonreciprocity at few-photon level typically requires strong symmetry breaking, posing significant experimental challenges. Here we demonstrate that phase-controlled quantu…

Dual-mode ground-state cooling in quadratic optomechanical systems: from multistability to general dark-mode suppression
Huanhuan Wei, Yun Chen, Jing Tang +1
We theoretically investigate a quadratic optomechanical system comprising a single-mode optical cavity linearly coupled to one mechanical resonator and quadratically coupled to a s…

Tunable Single- and Multiphoton Bundles in Cavity-Coupled Atomic Arrays
Geng Zhao, Yun Chen, Jiayuang Zhang +2
We propose an experimentally accessible scheme for realizing tunable nonclassical light in cavity-coupled reconfigurable atomic arrays. By coherently controlling the collective int…
