  Using Monte Carlo simulation, we studied fractionalized phases in a model of
exciton bose condensate and found evidence for an emergent photon in a finite
size system. The fractionalized phase is a meta-stable Coulomb phase where an
emergent photon arises as a gapless collective excitation of the excitons. We
also studied a possibility of spiral* phase where fractionalization and long
range spiral order of the exciton condensate coexist.
