Photonic state engineering via energy-level crossing by giant atoms in topological waveguide QED setup
Mingzhu Weng, Gang Wang, Zhihai Wang
Photonic state engineering in waveguide QED is typically based on local light-matter interactions. This limits its control over the spatial structure of bound photonic states. Here…
Liouvillian gap closing--bound states in the continuum connection and diverse dynamics in a giant-atom waveguide QED setup
Hongwei Yu, Mingzhu Weng, Zhihai Wang +1
In open quantum systems, reduced dynamics is commonly described by a master equation, whose Liouvillian gap closing (LGC) typically signals the emergence of decoherence-free subspa…
Engineering photonic dispersion relation and atomic dynamics in waveguide QED setup via long-range hoppings
Weijun Cheng, Da-Wei Wang, Yang Xue +2
Non-trivial dispersion relations engineered in photonic waveguide for the precise control of atomic dynamics has recently attracted considerable attention. Here, we study a system…
Boundary-induced Phases in the Dissipative Dicke Lattice Model
Peng-Fei Wei, Yilun Xu, Fengxiao Sun +3
The superradiant phase transition in the dissipative Dicke lattice model, driven by on-site collective atom-photon interactions and inter-site photon hopping, is a cornerstone of n…
High-fidelity Generation of Bell and W States in Giant Atom System via Bound State in the Continuum
Mingzhu Weng, Hongwei Yu, Zhihai Wang
In this paper, we propose a high-fidelity scheme for generating entangled states in a system of two and three giant atoms coupled to the coupled resonator waveguide. Our approach l…
Rabi oscillation and fractional population via the bound states in the continuum in a giant atom waveguide QED setup
Hongwei Yu, Xiaojun Zhang, Zhihai Wang +1
We study the dynamics of two giant atoms interacting with a coupled resonator waveguide (CRW) beyond the Markovian approximation. The distinct atomic configurations determine the n…
