Polariton Exchange Interactions in Multichannel Optical Networks
Mohammad Khazali, Callum R. Murray, Thomas Pohl
We examine the dynamics of Rydberg polaritons with dipolar interactions that propagate in multiple spatial modes. The dipolar excitation exchange between different Rydberg states m…
Quantum and Nonlinear Optics in Strongly Interacting Atomic Ensembles
Callum R. Murray, Thomas Pohl
Coupling light to ensembles of strongly interacting particles has emerged as a promising route toward achieving few photon nonlinearities. One specific way to implement this kind o…
Photon Subtraction by Many-Body Decoherence
Callum R. Murray, Ivan Mirgorodskiy, Christoph Tresp +5
We experimentally and theoretically investigate the scattering of a photonic quantum field from another stored in a strongly interacting atomic Rydberg ensemble. Considering the ma…
Coherent photon manipulation in interacting atomic ensembles
Callum R. Murray, Thomas Pohl
Coupling photons to Rydberg excitations in a cold atomic gas yields unprecedentedly large optical nonlinearities at the level of individual light quanta, where the formation of nea…
Many-body decoherence dynamics and optimised operation of a single-photon switch
Callum R. Murray, Alexey V. Gorshkov, Thomas Pohl
We develop a theoretical framework to characterize the decoherence dynamics due to multi-photon scattering in an all-optical switch based on Rydberg atom induced nonlinearities. By…
