Description:
Title: Quantum many-body physics with atoms and photons
Tightly packed ordered arrays of atoms (or, more generally, quantum emitters) exhibit remarkable collective optical properties resulting from correlated dissipation in the form of photon emission. In this talk, I will discuss the single-, few- and many-body out-of-equilibrium optical physics of atomic arrays, and their potential to realize versatile light-matter interfaces. In particular, I will focus on subradiance (where atoms are “dark” and become decoupled from the radiative environment) and on its counterpart, superradiance (where atoms are “bright” and radiate much faster than a single atom would). I will finish by discussing the implications of collective light matter interaction in quantum information processing, nonlinear optics, and metrology.
