Exact solvability and two-frequency Rabi oscillation in cavity-QED setup with moving emitter
Mingzhu Weng, Zhihai Wang
In this paper, we investigate the energy spectrum and coherent dynamical process in a cavity-QED setup with a moving emitter, which is subject to a harmonic potential. We find that…
Cramér-Rao bound and quantum parameter estimation with non-Hermitian systems
Jianning Li, Haodi Liu, Zhihai Wang +1
The quantum Fisher information constrains the achievable precision in parameter estimation via the quantum Cramér-Rao bound, which has attracted much attention in Hermitian systems…
Quantum interferometry for rotation sensing in an optical microresonator
Weijun Cheng, Zhihai Wang, Xiaoguang Wang
We theoretically propose a scheme to perform rotation sensing in a Whispering-gallery-mode resonator setup. With the assistance of a large detuned two-level atom, which induces the…
Topology and retardation effect of a giant atom in a topological waveguide
Weijun Cheng, Zhihai Wang, Yu-xi Liu
The interaction between the quantum emitter and topological photonic system makes both the emitter and the photon behave in exotic ways. We here study a system that a giant atom is…
Phase-modulated Autler-Townes splitting in a giant-atom system within waveguide QED
Wei Zhao, Yan Zhang, Zhihai Wang
The nonlocal emitter-waveguide coupling, which gives birth to the so called giant atom, represents a new paradigm in the field of quantum optics and waveguide QED. In this paper, w…
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…
