Quantum transport in nonlinear Rudner-Levitov models
Lei Du, Jin-Hui Wu, M. Artoni +1
Quantum transport in a class of nonlinear extensions of the Rudner-Levitov model is numerically studied in this paper. We show that the quantization of the mean displacement, which…
Giant Atoms in a Synthetic Frequency Dimension
Lei Du, Yan Zhang, Jin-Hui Wu +2
Giant atoms that interact with real-space waveguides at multiple spatial points have attracted extensive attention due to their unique interference effects. Here we propose a feasi…
Quantum theory of photonic vortices and quantum statistics of twisted photons
Li-Ping Yang, Dazhi Xu
The topological charge of a photonic vortex is an essential quantity in singular optics and the critical parameter to characterize the vorticity of twisted light. However, the defi…
Exploring variational quantum eigensolver ansatzes for the long-range XY model
Jia-Bin You, Dax Enshan Koh, Jian Feng Kong +3
Finding the ground state energy and wavefunction of a quantum many-body system is a key problem in quantum physics and chemistry. We study this problem for the long-range XY model…
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…
Localization-enhanced dissipation in a generalized Aubry-André-Harper model coupled with Ohmic baths
H. T. Cui, M. Qin, L. Tang +2
In this work, the exact dynamics of excitation in the generalized Aubry-André-Harper model coupled with an Ohmic-type environment is discussed by evaluating the survival probabilit…
