Non-Hermitian Band Topology and Edge States in Atomic Lattices
Wenxuan Xie, John C Schotland
We investigate the band structure and topological phases of one- and two-dimensional bipartite atomic lattices mediated by long-range dissipative radiative coupling. By deriving an…

Band Structure and Dynamics of Single Photons in Atomic Lattices
Wenxuan Xie, John C. Schotland
We present a framework to investigate the collective properties of atomic lattices in one, two, and three dimensions. We analyze the single-photon band structure and associated ato…

Two-photon superradiance and subradiance
Wenxuan Xie, Imran Mirza, John C Schotland
We consider the problem of two-photon cooperative emission in systems of two-level atoms. Two physically distinct regimes are analyzed. First, we investigate the case of a small nu…
