Periodic quantum Rabi model with cold atoms at deep strong coupling
Geram R. Hunanyan, Johannes Koch, Stefanie Moll +3
The quantum Rabi model describes the coupling of a two-state system to a bosonic field mode. Recent theoretical work has pointed out that a generalized periodic version of this mod…
Two-photon excitation and absorption spectroscopy of gaseous and supercritical xenon
Thilo vom Hövel, Franz Huybrechts, Eric Boltersdorf +3
Spectroscopy of gases under high-pressure conditions is of interest in various fields such as plasma physics and astrophysics. Recently, it has also been proposed to utilize a high…
Quantum Rabi dynamics of trapped atoms far in the deep strong coupling regime
Johannes Koch, Geram R. Hunanyan, Till Ockenfels +3
The coupling of a two-level system with an electromagnetic field, whose fully quantized version is the quantum Rabi model, is among the central topics of quantum physics. When the…
Fluctuation dynamics of an open photon Bose-Einstein condensate
Fahri Emre Ozturk, Tim Lappe, Goran Hellmann +5
Bosonic gases coupled to a particle reservoir have proven to support a regime of operation where Bose-Einstein condensation coexists with unusually large particle-number fluctuatio…
Thermo-optical interactions in a dye-microcavity photon Bose-Einstein condensate
Hadiseh Alaeian, Mira Schedensack, Clara Bartels +2
Superfluidity and Bose-Einstein condensation are usually considered as two closely related phenomena. Indeed, in most macroscopic quantum systems, like liquid helium, ultracold ato…
Quantum Rabi model in the Brillouin zone with ultracold atoms
Simone Felicetti, Enrique Rico, Carlos Sabin +6
The quantum Rabi model describes the interaction between a two-level quantum system and a single bosonic mode. We propose a method to perform a quantum simulation of the quantum Ra…
