Light Manipulation via Tunable Collective Quantum States in Waveguide-Coupled Bragg and Anti-Bragg Superatoms
Zhengqi Niu, Wei Nie, Daqiang Bao +8
A many-body quantum system which consists of collective quantum states, such as superradiant and subradiant states, behaves as a multi-level superatom in light-matter interaction.…

Efficient single-photon directional transfer between waveguides via two giant atoms
Daqiang Bao, Zhirong Lin
We investigate the single-photon transport properties in a double-waveguide quantum electrodynamic system. We force the energy degeneracy of the collective states by adjusting the…
