Bose-Einstein condensation of photons and grand-canonical condensate fluctuations
Jan Klaers, Martin Weitz
We review recent experiments on the Bose-Einstein condensation of photons in a dye-filled optical microresonator. The most well-known example of a photon gas, photons in blackbody…
Absorption spectroscopy of xenon and ethylene-noble gas mixtures at high pressure: Towards Bose-Einstein condensation of vacuum ultraviolet photons
Christian Wahl, Rudolf Brausemann, Julian Schmitt +3
Bose-Einstein condensation is a phenomenon well known for material particles as cold atomic gases, and this concept has in recent years been extended to photons confined in microsc…
Bose-Einstein Condensation of Photons versus Lasing and Hanbury Brown-Twiss Measurements with a Condensate of Light
Julian Schmitt, Tobias Damm, David Dung +3
The advent of controlled experimental accessibility of Bose-Einstein condensates, as realized with e.g. cold atomic gases, exciton-polaritons, and more recently photons in a dye-fi…
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…
Calorimetry of a Bose-Einstein condensed photon gas
Tobias Damm, Julian Schmitt, Qi Liang +4
Phase transitions, as the condensation of a gas to a liquid, are often revealed by a discontinuous behavior of thermodynamic quantities. For liquid Helium, for example, a divergenc…
Real-space imaging of a topological protected edge state with ultracold atoms in an amplitude-chirped optical lattice
Martin Leder, Christopher Grossert, Lukas Sitta +3
Topological states of matter, as quantum Hall systems or topological insulators, cannot be distinguished from ordinary matter by local measurements in the bulk of the material. Ins…
