Fluctuations in the holographic superconductor

Abstract

We study fluctuations in the holographic superconductor model, both above and below the critical temperature where the various fields involved are coupled. In particular, we introduce the concept of intrinsic dynamics and explain its relevance to the problem. We then compute spectral functions for the intrinsic dynamics of the scalar and gauge bulk field away from the probe limit, in order to understand the effect of the coupling of the order parameter and the gauge field in the superconducting phase and analyze the low-energy dynamical behavior of the holographic superconductor model.
