Equilibrium properties of the electron glass
The subject of the electron glass has been evolving from a number of different directions so the terminology in the literature is not uniform. Fleishman and Anderson (1980) first referred to a system of disorder-localized electrons with Coulomb interactions as Fermi glass. Subsequently the term was used for noninteracting Anderson-localized electrons while in the presence of interactions such systems became known in a broad sense as the electron glass (or sometimes Coulomb glass), and it is used in this way here. Sometimes the term is used more narrowly referring to materials with localized interacting electrons exhibiting the glassy properties described in Chapter 7.
