Single-Photon Scattering in a Waveguide Coupled to a Giant Atom with Loss or Gain
Yu Xin, Jia-Ming Zhang, Bing Chen
This work investigates single-photon scattering in a one-dimensional coupled-resonator waveguide interacting with a giant atom with a complex on-site energy. Within the generalized…

Bound states and decay dynamics in -level Friedrichs model with factorizable interactions
Jia-Ming Zhang, Yu Xin, Bing Chen
Considering an -level system interacting factorizably with a continuous spectrum, we derive expressions for the bound states and the dynamical evolution within this single-excit…
