Condensed Matter Seminar, Karyn Le Hur, " Many-Bodied Quantum Physics with Photons"
In this Talk, we survey recent theoretical studies concerning the realization of many-body quantum physics with photons. First we introduce the Jaynes-Cummings lattice model and discuss the emergent Mott-Superfluid transition of light in electromagnetic resonator arrays which are under experimental investigation at Princeton in the group of Andrew Houck. Then, we show how to engineer artificial gauge fields for light and discuss related topological phases of photons in circuit QED systems. At a general level, transmission lines (long waveguides or Josephson junction arrays) can also be viewed as Ohmic dissipative baths that can also be used to engineer novel many-body physics with light. As an example, we discuss a way to emulate the spin-boson model or anisotropic Kondo model and we introduce the notion of photonic Kondo resonance obtained by sending microwave light in the underdamped limit.
