Enantiomeric excess determination based on nonreciprocal transition induced spectral line elimination
Xun-Wei Xu, Chong Ye, Yong Li +1
The spontaneous emission spectrum of a multi-level atom or molecule with nonreciprocal transition is investigated. It is shown that the nonreciprocal transition can lead to the eli…
Multiphoton blockade in the two-photon Jaynes-Cummings model
Fen Zou, Xiao-Ya Zhang, Xun-Wei Xu +2
We study multiphoton blockade and photon-induced tunneling effects in the two-photon Jaynes-Cummings model, where a single-mode cavity field and a two-level atom are coupled via a…
Nonreciprocity via nonlinearity and synthetic magnetism
Xun-Wei Xu, Yong Li, Baijun Li +2
We propose how to realize nonreciprocity for a weak input optical field via nonlinearity and synthetic magnetism. We show that the photons transmitting from a linear cavity to a no…
Nonreciprocal transition between two nondegenerate energy levels
Xun-Wei Xu, Yan-Jun Zhao, Hui Wang +2
Stimulated emission and absorption are two fundamental processes of light-matter interaction, and the coefficients of the two processes should be equal in general. However, we will…
Generation of single entangled photon-phonon pairs via an atom-photon-phonon interaction
Xun-Wei Xu, Hai-Quan Shi, Jie-Qiao Liao +1
Quantum blockade and entanglement play important roles in quantum information and quantum communication as quantum blockade is an effective mechanism to generate single photons (ph…
Optimal unidirectional amplification induced by optical gain in optomechanical systems
L. N. Song, Qiang Zheng, Xun-Wei Xu +2
We propose a three-mode optomechanical system to realize optical nonreciprocal transmission with unidirectional amplification, where the system consists of two coupled cavities and…
Nonreciprocal unconventional photon blockade in a spinning optomechanical system
Baijun Li, Ran Huang, Xun-Wei Xu +2
We propose how to achieve quantum nonreciprocity via unconventional photon blockade (UPB) in a compound device consisting of an optical harmonic resonator and a spinning optomechan…
