Observation of coherent coupling between super- and subradiant states of an ensemble of cold atoms collectively coupled to a single propagating optical mode
Riccardo Pennetta, Daniel Lechner, Martin Blaha +3
We discuss the evolution of the quantum state of an ensemble of atoms that are coupled via a single propagating optical mode. We theoretically show that the quantum state of N atom…
Collective radiative dynamics of an ensemble of cold atoms coupled to an optical waveguide
Riccardo Pennetta, Martin Blaha, Aisling Johnson +4
We experimentally and theoretically investigate collective radiative effects in an ensemble of cold atoms coupled to a single-mode optical nanofiber. Our analysis unveils the micro…
Beyond the Tavis-Cummings model: revisiting cavity QED with atomic ensembles
Martin Blaha, Aisling Johnson, Arno Rauschenbeutel +1
The interaction of an ensemble of two-level atoms with a single mode electromagnetic field is described by the Tavis-Cummings model. There, the collectively enhanced light-matt…
