Quantum many-body physics of photons in waveguide QED

Abstract: The generation and control of strongly interacting photons is a long-standing goal of quantum optics. In recent years, remarkable experiments with cavity QED platforms, strongly interacting Rydberg atoms, and circuit QED have demonstrated photon-photon interactions at the few-body level. In this talk I show that a conceptually simple platform of two-level atoms ideally coupled to a chiral photonic mode forms an exciting system for exploring the many-body physics of photons. Here, a class of bound photon eigenstates hold the key to understanding the dynamics of this system at the few- and many-body scale. I will show that one can use these states to describe the entire spectrum from few-photon quantum propagation, to genuine quantum many-body (atom and photon) phenomena, and ultimately the quantum-to-classical transition.
