Topology and retardation effect of a giant atom in a topological waveguide

W Cheng, Z Wang, Y Liu - Physical Review A, 2022 - APS
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 where a giant …

Non-Markovian relaxation of a three-level system: Quantum trajectory approach

J **g, T Yu - Physical review letters, 2010 - APS
The non-Markovian dynamics of a three-level quantum system coupled to a bosonic
environment is a difficult problem due to the lack of an exact dynamic equation such as a …

Entanglement preparation and nonreciprocal excitation evolution in giant atoms by controllable dissipation and coupling

H Yu, Z Wang, JH Wu - Physical Review A, 2021 - APS
We investigate the dynamics of a giant atom (or atoms) in a waveguide QED scenario,
where the atom couples to the coupled resonator waveguide via two sites. For a single-giant …
