Photonic Band Structure of Two-dimensional Atomic Lattices
Janos Perczel, Johannes Borregaard, Darrick E. Chang +4
Two-dimensional atomic arrays exhibit a number of intriguing quantum optical phenomena, including subradiance, nearly perfect reflection of radiation and long-lived topological edg…
One- and two-axis squeezing of atomic ensembles in optical cavities
Johannes Borregaard, Emily D. Davis, Greg S. Bentsen +2
The strong light-matter coupling attainable in optical cavities enables the generation of highly squeezed states of atomic ensembles. It was shown in [Phys. Rev. A 66, 022314 (2002…
Topological Quantum Optics in Two-Dimensional Atomic Arrays
Janos Perczel, Johannes Borregaard, Darrick E. Chang +4
We demonstrate that two-dimensional atomic emitter arrays with subwavelength spacing constitute topologically protected quantum optical systems where the photon propagation is robu…
