please see below for abstract -- Anatoly may be around for lunch discussions as well

look forward to seeing you

Best, Vadim

Realization of Bose-Einstein (quasi-)condensation of light in 2D [1] provides a new platform for
studying novel phases and phase transitions with no analogy in other condensed matter
systems. One of the phases is the condensate of photon pairs induced solely by the
orientational disorder of the dye molecules. This phase does not require any attraction
between photons. The condensation of photons can proceed through the phase separation
effect induced by equilibration of the dye molecules simultaneously with the formation of the
photonic condensate.
