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…

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…
