Stimulated superconductivity at strong coupling

TL;DR

This paper explores how time-dependent stimulation can enhance superconductivity, demonstrating that increasing the frequency of such sources can parametrically raise the transition temperature in holographic superconductor models.

Contribution

It extends the understanding of stimulated superconductivity by analyzing its effects within holographic models, revealing a regime where transition temperature increases with source frequency.

Findings

Transition temperature increases with frequency of time-dependent source

Holographic superconductors exhibit parametric enhancement of critical temperature

Stimulated superconductivity can be analyzed using holographic duality

Abstract

Stimulating a system with time dependent sources can enhance instabilities, thus increasing the critical temperature at which the system transitions to interesting low-temperature phases such as superconductivity or superfluidity. After reviewing this phenomenon in non-equilibrium BCS theory (and its marginal fermi liquid generalization) we analyze the effect in holographic superconductors. We exhibit a simple regime in which the transition temperature increases parametrically as we increase the frequency of the time-dependent source.
