Possible Pressure Effect for Superconductors

TL;DR

This paper estimates how high-pressure effects could influence the critical temperature of superconductors using thermodynamics and Pippard's length scale, revealing a parabolic relationship between pressure and Tc increase.

Contribution

It introduces a theoretical approach combining thermodynamics and Pippard's length scale to estimate pressure-induced Tc changes in superconductors.

Findings

Pressure increases can induce a parabolic change in Tc.

Theoretical estimates provide a range for pressure effects on superconductivity.

The approach offers a framework for predicting pressure effects in superconducting materials.

Abstract

We make an estimate of the possible range of $\Delta T_c$ induced by high-pressure effects in post-metallic superconductors by using the theory of {\it extended irreversible/reversible thermodynamics} and Pippard's length scale. The relationship between the increment of the superconducting temperature and the increase of the pressure is parabolic.
