Fluctuations of a Photon Bose-Einstein Condensate Coupled to a Reservoir: Describing Coherence Properties in a Free-Energy Model
Martin Weitz, Andreas Redmann, Riccardo Panico +4
Photons are mutually nearly noninteracting particles, so thermalized photon ensembles are commonly obtained not from direct particle-particle-interactions but rather from contact w…
Thermodynamics and State Preparation in a Two-State System of Light
Christian Kurtscheid, Andreas Redmann, Frank Vewinger +2
The coupling of two-level quantum systems to the thermal environment is a fundamental problem, with applications ranging from qubit state preparation to spin models. However, for t…
Bose-Einstein Condensation of Photons in a Four-Site Quantum Ring
Andreas Redmann, Christian Kurtscheid, Niels Wolf +3
Thermalization of radiation by contact to matter is a well-known concept, but the application of thermodynamic methods to complex quantum states of light remains a challenge. Here…
Compressibility and the Equation of State of an Optical Quantum Gas in a Box
Erik Busley, Leon Espert Miranda, Andreas Redmann +5
The compressibility of a medium, quantifying its response to mechanical perturbations, is a fundamental property determined by the equation of state. For gases of material particle…
Realizing arbitrary trapping potentials for light via direct laser writing of mirror surface profiles
Christian Kurtscheid, David Dung, Andreas Redmann +5
The versatility of quantum gas experiments greatly benefits from the ability to apply variable potentials. Here we describe a method which allows the preparation of potential struc…
