Query: Decondensation in non-equilibrium photonic condensates: when less is
  more   We investigate the steady state of a system of photons in a pumped dye-filled
microcavity. By varying pump and thermalization the system can be tuned between
Bose-Einstein condensation, multimode condensation, and lasing. We present a
rich non-equilibrium phase diagram which exhibits transitions between these
phases, including decondensation of individual modes under conditions that
would typically favor condensation.
