- Abstract: We develop a quantum optical formalism to treat a two-dimensional array of
atoms placed in an optical cavity. Importantly, and in contrast to typical
treatments, we account for cooperative dipole-dipole effects mediated by the
interaction of the atoms with the outside, non-cavity-confined modes. Based on
the observation that scattering to these modes is largely inhibited due to
these cooperative effects, we construct a generic formalism, independent of the
specific cavity structure, and apply it to an array of non-saturated atoms. By
further considering the atomic motion, we show that the inhibited damping can
lead to a favorable scaling of the optomechanical parameters of an atom-array
membrane placed within a cavity. The developed formalism lays the basis for
further investigation of many-body QED with atom arrays in transversely
confined geometries.

We observe a cavity dark mode, where the standing-wave nodes are dynamically locked to the positions of the atoms.
The dark mode is decoupled from the atoms, protecting the system from dissipation through atomic scattering.
We impart an arbitrary large phase shift on the converted optical fields by translating the atom array.

We show how photon-mediated interactions give rise to a plaquette-ordered bond pattern in the atomic ground state.
The pattern opens a non-trivial topological gap in 2D, resulting in a higher-order topological phase hosting corner states.
Our work shows how atomic quantum simulators can be harnessed to investigate novel strongly-correlated topological phenomena.
