The Holographic Disorder-Driven Superconductor-Metal Transition

Understand

We implement the effects of disorder on a holographic superconductor by introducing a random chemical potential on the boundary.

• We demonstrate explicitly that increasing disorder leads to the formation of islands where the superconducting order is enhanced and subsequently to the transition to a metal.
• We study the behavior of the superfluid density and of the conductivity as a function of the strength of disorder.
• We find explanations for various marked features in the conductivities in terms of hydrodynamic quasi-normal modes of the holographic superconductors.
