Spatial correlation of two-dimensional Bosonic multi-mode condensates
Wolfgang H. Nitsche, Na Young Kim, Georgios Roumpos +4
We studied the spatial coherence of a Bosonic two-dimensional multi-mode condensate both through measurements and simulations. It is shown that condensates with a constant spatial…
Algebraic order and the Berezinskii-Kosterlitz-Thouless transition in an exciton-polariton gas
Wolfgang H. Nitsche, Na Young Kim, Georgios Roumpos +5
We observe quasi-long range coherence in a two-dimensional condensate of exciton-polaritons. Our measurements are the first to confirm that the spatial correlation algebraically de…
Gain-induced trapping of microcavity exciton polariton condensates
Georgios Roumpos, Wolfgang H. Nitsche, Sven Hoefling +2
We have performed real and momentum space spectroscopy of exciton polariton condensates in a GaAs-based microcavity under non-resonant excitation with an intensity stabilized laser…
