DESCRIPTION:Speaker: Alexander N. Poddubny\nhosted by Johannes Fink / Elena
  Redchenko\nAbstract: We study theoretically  propagation of a photon pair
   in a one-dimensional  waveguide with an embedded array of closely-spaced
  two-level atoms. We predict\, that atom-mediated interaction between the 
 two photons enables an unexpectedly rich variety of two-quantum states. Th
 is  strikingly simple setup features  interaction-induced localization [ar
 Xiv: 1911.04113\, PRL (2020\, in press)]\,  quantum Hall phase with Landau
  levels\, interaction-driven topological edge states and Hofstadter-like b
 utterfly as well as signatures of quantum chaos.Our findings  enrich the u
 nderstanding of many-body quantum matter and open new avenues to engineer 
 entanglement by interactions.
