A Holographic Superconductor in an External Magnetic Field

Albash, Tameem, Johnson, Clifford V.

Understand

We study a system of a complex charged scalar coupled to a Reissner-Nordstrom black hole in 3+1 dimensional anti-de Sitter spacetime, neglecting back-reaction.

  • With suitable boundary conditions, the cases of a neutral and purely electric black hole have been studied in various limits and were shown to yield key elements of superconductivity in the dual 2+1 dimensional field theory, forming a condensate below a critical temperature.
  • By adding magnetic charge to the black hole, we immerse the superconductor into an external magnetic field.
  • We show that a family of condensates can form and we examine their structure.
