Excited states of holographic superconductors
Abstract In this paper we re-investigate the model of the anti-de Sitter gravity coupled to Maxwell and charged scalar fields, which has been studied as the gravitational dual to a superconductor for a long time since the famous work [Phys. Rev. Lett. 101 (2008) 031601]. By numerical method, we pres...
