AdS/CFT superconductors with Power Maxwell electrodynamics: reminiscent of the Meissner effect

TL;DR

This paper analytically investigates holographic s-wave superconductors with Power Maxwell electrodynamics in a D-dimensional Schwarzschild AdS space, revealing how external magnetic fields influence condensation and how scalar mass affects critical magnetic field strength.

Contribution

It introduces Power Maxwell electrodynamics into holographic superconductor models and analyzes the effects of external magnetic fields on condensation analytically.

Findings

Condensation occurs only below a critical magnetic field strength.

Critical field strength increases with scalar particle mass.

Condensation is harder to form as scalar mass increases.

Abstract

Based on an analytic scheme and neglecting the back reaction effect several crucial properties of holographic $ s $- wave superconductors have been investigated in the presence of an external magnetic field in the background of a $ D $ dimensional Schwarzschild AdS space time. Inspired by low energy limit of heterotic string theory, in the present paper we replace the conventional Maxwell action by a Power Maxwell action. Immersing the holographic superconductors in an external static magnetic field the spatially dependent condensate solutions have been obtained analytically. Interestingly enough it is observed that condensation can form only below a certain critical field strength ($ B_c $). Finally, and most importantly it is observed that the value of this critical field strength increases as the mass of the scalar particles gets higher, which indicates the onset of a harder condensation.
