Query: Long range correlations in a 97% excitonic one-dimensional polariton
  condensate   We report on the realization of an out-of-equilibrium polariton condensate
under pulsed excitation in a one-dimensional geometry. We observe macroscopic
occupation of a polaritonic mode with only 3% photonic fraction, and a nature
strikingly close to that of a bare exciton condensate. With the help of this
tiny photonic fraction, the condensate is found to display first-order
coherence over distances as large as 10 microns. Based on a driven-dissipative
mean field model, we find that the correlations length is limited by the
effects of a shallow disorder under non-equilibrium conditions.
