摘要：

Classical SU(2) Yang-Mills theory in 3 + 1 dimensional anti-de Sitter space is known to provide a holographic dual to a 2 + 1 system that undergoes a superconducting phase transition. We study the electrical conductivity and spectral density of an isotropic superconducting phase. We show that the theory exhibits a pseudogap at low temperatures and a nonzero Hall conductivity. The Hall conductivity is possible because of spontaneous breaking of time reversal symmetry.
