Self-consistent cluster CPA methods and the nested CPA theory
C. I. Ventura, R. A. Barrio, .
The coherent potential approximation, CPA, is a useful tool to treat systems with disorder. Cluster theories have been proposed to go beyond the translation invariant single-site C…

Intermediate Valence Model for the Colossal Magnetoresistance in Tl_{2}Mn_{2}O_{7}
C. I. Ventura, B. Alascio
The colossal magnetoresistance exhibited by Tl_{2}Mn_{2}O_{7} is an interesting phenomenon, as it is very similar to that found in perovskite manganese oxides although the compound…

Propagation of a hole on a Neel background
E. Mueller-Hartmann, C. I. Ventura
We analyze the motion of a single hole on a Néel background, neglecting spin fluctuations. Brinkman and Rice studied this problem on a cubic lattice, introducing the retraceable-pa…
