Observation of emergent photon in Monte Carlo simulation of exciton condensate
arXiv:cond-mat/0603625 · doi:10.1103/PhysRevB.74.035107
Abstract
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.
