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…

Controllable optical response and tunable sensing based on self interference in waveguide QED systems

Lei Du, Zhihai Wang, Yong Li

We study the self interference effect of a resonator coupled with a bent waveguide at two separated ports. Such interference effects are shown to be similar for the cases of standi…

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…

Dynamical evolution of an effective two-level system with PT symmetry

Lei Du, Zhihao Xu, Chuanhao Yin +1

We investigate the dynamics of parity- and time-reversal (PT ) symmetric two-energy-level atoms in the presence of two optical and a radio-frequency (rf) fields. The strength and r…
