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…
