Topics in the Theory of Superconductivity

Abstract

<p> Simple theoretical expressions for the zero temperature energy gap and the transition temperature of a weak coupling superconductor are derived and applied to an investigation of several phenomena.</p> <p> The anisotropy of the energy gap in aluminium arising from the anisotropy in the phonon spectrum is calculated. The effect of this energy gap anisotropy on some thermodynamic properties of superconducting aluminium is investigated.</p>
