The modification of exponents in the Ginzburg-Sobyanin theory of superfluidity

TL;DR

This paper proposes a modification to the Ginzburg-Sobyanin theory of superfluidity that adjusts temperature dependencies to align critical exponents with phase transition theory and experimental data.

Contribution

It introduces a new amendment to the theory's temperature dependencies, improving its consistency with fluctuation theory and empirical observations.

Findings

Critical exponents match fluctuation theory predictions.

Enhanced agreement with experimental data.

Theoretical framework now more accurately describes superfluid phase transitions.

Abstract

A suggested amendment to the temperature dependencies in the thermodynamic potential of the Ginzburg-Sobyanin theory of superfluidity, which makes it possible to obtain critical exponents that are consistent with the general relations of the fluctuation theory of phase transitions, as well as with modern experimental and calculated data.
