Marc Montull, Oriol Pujolas, Alberto Salvio, Pedro J. Silva
TL;DR
This paper explores flux periodicities in holographic superconductors, revealing a transition from hc/2e to hc/e periodicity linked to classical no-hair theorems and providing a Ginzburg-Landau explanation.
Contribution
It demonstrates flux periodicity phenomena in holographic superconductors and connects them to classical no-hair theorems, offering a new theoretical perspective.
Findings
Holographic superconductors exhibit flux periodicity transition.
Periodicities depend on Aharonov-Bohm effect suppression.
Ginzburg-Landau theory explains period-doubling phenomenon.
Abstract
Superconductors in a cylindrical geometry respond periodically to a cylinder-threading magnetic flux, with the period changing from hc/2e to hc/e depending on whether the Aharonov-Bohm effects are suppressed or not. We show that Holographic Superconductors present a similar phenomenon, and that the different periodicities follow from classical no-hair theorems. We also give the Ginzburg-Landau description of the period-doubling phenomenon.
