Electron Correlation in Metals

Electron Correlation in Metals

The recent development of theory on electron correlation in metals is explained in detail in this book. The strongest interaction between electrons in metals is the Coulomb repulsive force. This interaction gives rise to magnetism such as the ferromagnetism in Fe, Co and Ni. This interaction also induces the metal-insulator transition called the Mott transition. Surprisingly, recent studies confirm that the repulsive interaction is the origin of high temperature superconductivity in copper-oxide systems. Moreover, the number of new superconducting systems due to the electron correlation are rapidly increasing.


Electron Correlation in Metals could serve as a supplementary reference in a graduate-level, special-topics course in condensed matter theory. When confronting a new problem, it is often instructive to take a first stab at it using perturbative techniques - and for that, Yamada is indeed an expert.

"Yamada carefully explains all...with the aid of many helpful diagrams, and thoroughly describes the numerous consequences of these correlated electron movements, especially magnetic behaviour and superconductivity."
