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…
Observation of first and second sound in a BKT superfluid
Panagiotis Christodoulou, Maciej Gałka, Nishant Dogra +3
Superfluidity in its various forms has fascinated scientists since the observation of frictionless flow in liquid helium II. In three spatial dimensions (3D), it is conceptually as…
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…
