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.
