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…
Fluctuation dynamics of an open photon Bose-Einstein condensate
Fahri Emre Ozturk, Tim Lappe, Goran Hellmann +5
Bosonic gases coupled to a particle reservoir have proven to support a regime of operation where Bose-Einstein condensation coexists with unusually large particle-number fluctuatio…
Dynamics and correlations of a Bose-Einstein condensate of photons
Julian Schmitt
The Tutorial reports recent experimental advances in studies of the dynamics as well as the number and phase correlations of a Bose-Einstein condensed photon gas confined in a high…
Elliptic flow in a strongly-interacting normal Bose gas
Richard J. Fletcher, Jay Man, Raphael Lopes +6
We study the anisotropic, elliptic expansion of a thermal atomic Bose gas released from an anisotropic trapping potential, for a wide range of interaction strengths across a Feshba…
Variable Potentials for Thermalized Light and Coupled Condensates
David Dung, Christian Kurtscheid, Tobias Damm +4
For over a decade, cold atoms in lattice potentials have been an attractive platform to simulate phenomena known from solid state theory, as the Mott-insulator transition. In contr…
