Does one need to consider superconductivity as Bose-Einstein condensation?

TL;DR

This paper proposes that the temperature dependence of the energy gap in superconductors can be viewed as an order-disorder transition, linking critical temperature and magnetic field in a way consistent with experimental data.

Contribution

It introduces a new perspective by classifying superconductivity as an order-disorder transition and derives a relationship aligning with observed measurements.

Findings

Energy gap temperature dependence resembles an order-disorder transition

Derived relationship matches experimental critical temperature and magnetic field data

Supports viewing superconductivity through the lens of phase transition theory

Abstract

It is shown that the temperature dependence of the value of energy gap in superconductors can be classified as the order-disorder transition with its characteristic features. The obtained relationship between the critical temperature and the critical magnetic field of the condensate of electrically charged particles is in accordance with measurement data of superconductors.
