Spectroscopy of high pressure rubidium-noble gas mixtures
Till Ockenfels, Paško Roje, Thilo vom Hövel +2
Spectroscopy of alkali-buffer gas mixtures at high pressures from single-digit to several 100 bars in the regime of substantial collisional broadening is relevant in a wide range o…
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…
Sapphire optical viewport for high pressure and temperature applications
Till Ockenfels, Frank Vewinger, Martin Weitz
We describe the design of a soldered sapphire optical viewport, useful for spectroscopic applications of samples at high temperatures and high pressures. The sapphire window is bon…
Rubidium spectroscopy at high-pressure buffer gas conditions: detailed balance in the optical interaction of an absorber coupled to a reservoir
Stavros Christopoulos, Peter Moroshkin, Lars Weller +5
Optical spectroscopy of atoms and molecules is a field where one usually operates very far from thermal equilibrium conditions. A prominent example is spectroscopy of thin vapors,…
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…
