Light-matter interaction at the transition between cavity and waveguide QED
Daniel Lechner, Riccardo Pennetta, Martin Blaha +3
Experiments based on cavity quantum electrodynamics (QED) are widely used to study the interaction of a light field with a discrete frequency spectrum and emitters. More recently,…
The Jaynes-Cummings model breaks down when the cavity significantly reduces the emitter's free-space emission rate
Martin Blaha, Arno Rauschenbeutel, Jürgen Volz
Strong coupling between a single resonator mode and a single quantum emitter is key to a plethora of experiments and applications in quantum science and technology and is commonly…
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…
Observation of Multimode Strong Coupling of Cold Atoms to a 30-m Long Optical Resonator
Aisling Johnson, Martin Blaha, Alexander E. Ulanov +3
We report on the observation of multimode strong coupling of a small ensemble of atoms interacting with the field of a 30-m long fiber resonator containing a nanofiber section. The…
