Analytical study of holographic superconductor with backreaction in 4d Gauss-Bonnet gravity

Abstract

In this paper we have analytically investigated holographic superconductors in four dimensional Einstein-Gauss-Bonnet gravity background. Recently the novel four dimensional Einstein-Gauss-Bonnet gravity has been formulated by rescaling the Gauss-Bonnet coupling constant α→αd−4 and taking the limit d→4, and this predicts several interesting new features. To know the effect of the curvature correction on the (2+1)-dimensional holographic superconductors, we have considered (3+1)-dimensional Einstein-Gauss-Bonnet gravity. Using the Sturm-Liouville eigenvalue approach, the critical temperature and the condensation operator values has been investigated in this framework away from the probe limit. We reproduce the numerical results from our analytical investigation.
