“…The r, of Pb was found not to change, and that of Hg to decrease slightly. Matthias et al (1956) studied solid solutions with up to 50% of chemical scattering centers. In cases where the electron concentration was not expected to change much in the alloying process, they found T, values comparable to those of the pure materials.…”

The interacting disordered electron problem is reviewed with emphasis on the quantum phase transitions that occur in a model system and on the field-theoretic methods used to describe them. An elementary discussion of conservation laws and diffusive dynamics is followed by a detai1ed derivation of the extended nonlinear sigma model, which serves as an effective field theory for the problem. A general scaling theory of metal-insulator and related transitions is developed, and explicit renormalization-group calculations for the various universality classes are reviewed and compared with experimental results. A discussion of pertinent physical ideas and phenomenological approaches to the metal-insulator transition not contained in the sigma-model approach is given, and phase-transition aspects of related problems, like disordered superconductors and the quantum Hall effect, are discussed. The review concludes with a list of open problems.

“…One of the most important early experimental results was the robustness of the conventional superconductivity to small concentrations of non-magnetic impurities (De Haas and Voogd, 1931;Lazarev et al, 1957;Matthias et al, 1956). The theoretical underpinning of this result is now known as Anderson's theorem (Anderson, 1959a,b).…”
