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-damping of isolated, oscillating Bose-Einstein condensates
Tim Lappe, Anna Posazhennikova, Johann Kroha
Experiments on the nonequilibrium dynamics of an isolated Bose-Einstein condensate (BEC) in a magnetic double-well trap exhibit a puzzling divergence: While some show dissipation-f…
