Single-photon frequency conversion via a giant -type atom
Lei Du, Yong Li
We study single-photon scattering via a giant -type atom, where both atomic transitions are coupled with the modes of a single waveguide at two separated points. The giant-atom…
Single-photon nonreciprocal excitation transfer with non-Markovian retarded effects
Lei Du, Mao-Rui Cai, Jin-Hui Wu +2
We study at the single-photon level the nonreciprocal excitation transfer between emitters coupled with a common waveguide. Non-Markovian retarded effects are taken into account du…
Nonreciprocal quantum interference and coherent photon routing in a three-port optomechanical system
Lei Du, Yao-Tong Chen, Jin-Hui Wu +1
We study the quantum interference between different weak signals in a three-port optomechanical system, which is achieved by coupling three cavity modes to the same mechanical mode…
Phase controlled single-photon nonreciprocal transmission in a one-dimensional waveguide
Zhihai Wang, Lei Du, Yong Li +1
We study the controllable single-photon scattering via a one-dimensional waveguide which is coupled to a two-level emitter and a single-mode cavity simultaneously. The emitter and…
All-optical photon transmission switching in a passive-active optomechanical system
Lei Du, Yi-Mou Liu, Yan Zhang +1
We propose a feasible scheme to realize all-optical photon transmission switching in a passiveactive optomechanical system, consisting of one ordinary passive cavity, one active ca…
