Building an AdS/CFT superconductor
arXiv:0803.3295 · doi:10.1103/PhysRevLett.101.031601
Abstract
We show that a simple gravitational theory can provide a holographically dual description of a superconductor. There is a critical temperature, below which a charged condensate forms via a second order phase transition and the (DC) conductivity becomes infinite. The frequency dependent conductivity develops a gap determined by the condensate. We find evidence that the condensate consists of pairs of quasiparticles.
