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…
A Sunlight-pumped Two-dimensional Thermalized Photon Gas
Erik Busley, Leon Espert Miranda, Christian Kurtscheid +4
The Liouville theorem states that the phase-space volume of an ensemble in a closed system remains constant. While gases of material particles can efficiently be cooled by sympathe…
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…
Thermally Condensing Photons into a Coherently Split State of Light
Christian Kurtscheid, David Dung, Erik Busley +3
Techniques to control the quantum state of light play a crucial role in a wide range of fields, from quantum information science to precision measurements. While for electrons in s…
