Non-ohmic critical fluctuation conductivity of layered superconductors in magnetic field

TL;DR

This paper investigates how thermal fluctuation conductivity in layered superconductors is affected by simultaneous perpendicular magnetic and in-plane electric fields, revealing a combined suppression effect on superconducting fluctuations.

Contribution

It introduces a self-consistent Hartree approximation to analyze the combined impact of magnetic and electric fields on fluctuation conductivity in layered superconductors.

Findings

Simultaneous fields cause stronger fluctuation suppression than individual fields.

The model applies to arbitrarily strong in-plane electric fields.

Results enhance understanding of fluctuation behavior under combined external fields.

Abstract

Thermal fluctuation conductivity for a layered superconductor in perpendicular magnetic field is treated in the frame of the self-consistent Hartree approximation for an arbitrarily strong in-plane electric field. The simultaneous application of the two fields results in a slightly stronger suppression of the superconducting fluctuations, compared to the case when the fields are applied individually.
