Vacuum-Ultraviolet Absorption and Emission Spectroscopy of Gaseous, Liquid, and Supercritical Xenon
Christian Wahl, Marvin Hoffmann, Thilo vom Hoevel +2
Bose-Einstein condensation, an effect long known for material particles as cold atomic gases, has in recent years also been observed for photons in microscopic optical cavitites. H…
Observation of a non-Hermitian phase transition in an optical quantum gas
Fahri Emre Öztürk, Tim Lappe, Göran Hellmann +5
Quantum gases of light, as photons or polariton condensates in optical microcavities, are collective quantum systems enabling a tailoring of dissipation from e.g. cavity loss. This…
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…
