Holographic Superconductors and Higher Curvature Corrections

TL;DR

This paper investigates how higher curvature corrections in a holographic superconductor model affect its critical temperature, condensate behavior, and conductivity, revealing that positive curvature couplings hinder condensation and alter universal conductivity ratios.

Contribution

It introduces a fully backreacted holographic superconductor model with higher curvature interactions and analyzes their impact on physical properties.

Findings

Positive higher curvature couplings increase the difficulty of condensation.

Higher curvature corrections cause deviations from universal conductivity ratios.

The model provides insights into the effects of curvature corrections on holographic superconductors.

Abstract

We study a fully backreacted holographic model of a four-dimensional superconductor by including a higher curvature interaction in the bulk action. We study how the critical temperature and the field theory condensate vary in this model and conclude that positive higher curvature couplings make the condensation harder. We also compute the conductivity, finding significant deviations from the conjectured universal frequency gap to critical temperature ratio.
