How do atoms radiate together? Although in general this is still an open question, addressing the 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. Combining quantumcoherence with strong collective optical and mechanical responses, atomic arrays should open new ways in
manipulating the quantum state of light and atoms, and to systematically study the quantum many-body
phenomena of collective light-matter interactions.
