The electron glass / Michael Pollak, Department of Physics, University of California, Riverside, Miguel Ortuño, Departamento de F'isica, Universidad de Murcia, Aviad Frydman, Department of Physics, Bar Ilan University.

"Presenting an up-to-date report on electronic glasses, this book examines experiments and theories for a variety of disordered materials where electrons exhibit glassy properties. Some interesting mathematical models of idealized systems are also discussed. The authors examine problems in this field, highlighting which issues are currently understood and which require further research. Where appropriate, the authors focus on physical arguments over elaborate derivations. The book provides introductory background material on glassy systems, properties of disordered systems and transport properties so it can be understood by researchers in condensed matter physics who are new to this field"-- Provided by publisher.
