Influence of Disorder on Electron-Hole Pair Condensation in Graphene Bilayers

Graphene bilayers can condense into a state with spontaneous interlayer phase coherence that supports dissipationless counterflow supercurrents. Here, we address the influence of disorder on the graphene bilayer mean field and Kosterlitz-Thouless critical temperatures and report on a simple criteria for the survival of pair condensation.
