2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/109492Using 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.9 pages, 7 figures; V2 : correction made in Eq.(5); v3 : figure quality improvedStrongly Correlated Electronstext
