Configuration-based understanding of superradiant phase transitions in Dicke lattices
Peng-Fei Wei, Zhihai Wang
The emergence of multiple superradiant phases in Dicke lattice models has attracted considerable attention in the quantum optics community. However, a unified understanding of the…
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…
