Helical superconducting black holes

arXiv:1203.0533 · doi:10.1103/PhysRevLett.108.211601

Abstract

We construct novel static, asymptotically black hole solutions with Bianchi VII symmetry that are holographically dual to superconducting phases in four spacetime dimensions with a helical p-wave order. We calculate the precise temperature dependence of the pitch of the helical order. At zero temperature the black holes have vanishing entropy and approach domain wall solutions that reveal homogenous, non-isotropic dual ground states with emergent scaling symmetry.
