Nonclassical Light from Exciton Interactions in a Two-Dimensional Quantum Mirror
Valentin Walther, Lida Zhang, Susanne F. Yelin +1
Excitons in a semiconductor monolayer form a collective resonance that can reflect resonant light with extraordinarily high efficiency. Here, we investigate the nonlinear optical p…

Photon-photon interactions in Rydberg-atom arrays
Lida Zhang, Valentin Walther, Klaus Mølmer +1
We investigate the interaction of weak light fields with two-dimensional lattices of atoms, in which two-photon coupling establishes conditions of electromagnetically induced trans…
