Holographic Superconductors with Lifshitz Scaling
Black holes in asymptotically Lifshitz spacetime provide a window onto finite temperature effects in strongly coupled Lifshitz models. We add a Maxwell gauge field and charged matter to a recently proposed gravity dual of 2+1 dimensional Lifshitz theory. This gives rise to charged black holes with scalar hair, which correspond to the superconducting phase of holographic superconductors with z >...
متن کاملHolographic superconductors
It has been shown that a gravitational dual to a superconductor can be obtained by coupling anti-de Sitter gravity to a Maxwell field and charged scalar. We review our earlier analysis of this theory and extend it in two directions. First, we consider all values for the charge of the scalar field. Away from the large charge limit, backreaction on the spacetime metric is important. While the qua...
متن کاملHolographic Superconductors with Various Condensates
We extend earlier treatments of holographic superconductors by studying cases where operators of different dimension condense in both 2 + 1 and 3 + 1 superconductors. We also compute a correlation length. We find surprising regularities in quantities such as ωg/Tc where ωg is the gap in the frequency dependent conductivity. In special cases, new bound states arise corresponding to vector normal...
متن کاملGeneralizing Holographic Superconductors
We consider a family of holographically dual models of superconductivity to test the robustness of holographic superconductor models in general. Following the treatment of Hartnoll et al. and Albrecht et al., we introduce the basic holographic model and then develop a family of similar models by varying a parameter in the spacetime metric of the holographic theory. We then calculate several obs...
متن کاملHydrodynamics of Holographic Superconductors
We study the poles of the retarded Green functions of a holographic superconductor. The model shows a second order phase transition where a charged scalar operator condenses and a U(1) symmetry is spontaneously broken. The poles of the holographic Green functions are the quasinormal modes in an AdS black hole background. We study the spectrum of quasinormal frequencies in the broken phase, wher...
