Spectral and transport properties of correlated electrons in disordered alloys
Pokorný, Vladislav ; Janiš, Václav (advisor) ; Velický, Bedřich (referee) ; Markoš, Peter (referee)
We develop methods how to calculate charge transport in disordered systems applicable in all disorder regimes. They allow to calculate vertex corrections to the electrical conductivity and the diffusion coefficient in models of elastically scattered electrons in the presence of random scatterers. These methods are based on an asymptotic limit to high spatial dimensions. The resulting formulas lead to reliable results free of unphysical behavior, as illustrated on a gallery of numerical examples.
