Anomalous metallic behavior in strongly correlated electron systems

Many of the most important and challenging problems in modern solid state physics are in the regime where both the electron-electron interaction and disorder effects appear to be equally important. The dynamical mean field theory is ideally suited to treat both of these effects on equal footing. This book presents a theoretical study of several aspects of behavior of strongly correlated electron systems with disorder. First the influence of strong electron-electron interactions on the impurity dominated resistivity is examined and a possible relevance of the results for the physics of high mobility MOSFETs is discussed. Second part of the book describes a mechanism of disorder-driven non-Fermi liquid behavior in heavy fermion systems. The interplay of the Kondo effect and the RKKY interactions in disordered systems is examined within an extended dynamical mean field theory methods.
