## Abstract

We have derived the expression for the specific heat by using Ginzburg-Landau (GL) theory by taking $\\mid \\psi \\mid^{4}$ into account in the Hartree approximation. Without this term, the specific heat diverges at $T=T\_{c}(B)$. It is also shown that width and shape of the transition depends on the value of $\\alpha$ and $\\beta$, the coefficients in the GL free energy.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
