Model to Explain Large Changes in the Electronic Density of States with Atomic Ordering inV3Au

The superconducting transition temperature of ${\mathrm{V}}_3$Au has been experimentally shown to vary by a factor of 300, depending on the degree of atomic ordering. This has previously been attributed to a change in the electronic density of states $n\left(E\right)\mathrm{}$ with ordering. A model is proposed here which provides a theoretical basis for this change in $n\left(E\right)\mathrm{}$ with ordering.
