Holographic superconductors in 4D Einstein-Gauss-Bonnet gravity with backreactions

We construct the holographic superconductors away from the probe limit in the consistent D→4 Einstein-Gauss-Bonnet gravity. We observe that, both for the ground state and excited states, the critical temperature first decreases then increases as the curvature correction tends towards the Chern-Simon...

description	We construct the holographic superconductors away from the probe limit in the consistent D→4 Einstein-Gauss-Bonnet gravity. We observe that, both for the ground state and excited states, the critical temperature first decreases then increases as the curvature correction tends towards the Chern-Simons limit in a backreaction dependent fashion. However, the decrease of the backreaction, the increase of the scalar mass, or the increase of the number of nodes will weaken this subtle effect of the curvature correction. Moreover, for the curvature correction approaching the Chern-Simons limit, we find that the gap frequency ωg/Tc of the conductivity decreases first and then increases when the backreaction increases in a scalar mass dependent fashion, which is different from the finding in the (3+1)-dimensional superconductors that increasing backreaction increases ωg/Tc in the full parameter space. The combination of the Gauss-Bonnet gravity and backreaction provides richer physics in the scalar condensates and conductivity in the (2+1)-dimensional superconductors.
