No oscillating subradiant correlations in a strongly driven quantum emitter array
Jiaming Shi, Nikita Leppenen, Ran Tessler +1
We theoretically study time-dependent correlations in a strongly driven array of two-level atoms, coupled to photons in a waveguide. We focus on the spectrum of the Lio…

Chiral Dissociation of Bound Photon Pairs for a Non-Hermitian Skin Effect
Jiaming Shi, Alexander N. Poddubny
We theoretically study the bound states of interacting photons propagating in a waveguide chirally coupled to an array of atoms. We demonstrate that the bound photon pairs can conc…

Topological nature of edge states for one-dimensional systems without symmetry protection
Janet Zhong, Heming Wang, Alexander N Poddubny +1
We numerically verify and analytically prove a winding number invariant that correctly predicts the number of edge states in one-dimensional, nearest-neighbor (between unit cells),…
