Abstract

How do atoms radiate together? Although still an open question in general, addressing this problem of collective light-matter interactions in specific cases can lead to important insights and applications. In my talk, I will discuss how the collective optical response of a 2D array of trapped atoms renders it as a new platform for quantum science, with potential applications in quantum technologies. In particular, I will show how a dilute 2D array, comprised of even just a few dozen atoms, can perfectly reflect and scatter light, leading to the possibility of observing for the first time opto-mechanical phenomena at the single-photon level. I will discuss how this may pave the way towards the realization of “quantum metamaterials” which can exhibit a quantum superposition of their macroscopic optical responses.
