Heavy Electrons in Metals
Abstract Many properties of metals are, stated in very simple terms, determined by the conduction electrons and their interaction with the ionic lattice forming the solid. The physical description of these properties poses therefore a many-body problem par excellence. The history of the physics of metals in particular but certainly also that of condensed matter in general, is characterized by many attempts to circumvent the rigorous solution of this problem. In view of the complexity of this problem, it seems surprising that models assuming free or nearly-free electrons are often quite successful in describing the salient features of thermal or transport properties of metals. It is clear, however, that as soon as quantitative answers are asked for, these models are by far inadequate and further sophistication in the form of considering interactions among the electrons themselves and with the crystal lattice must be envisaged.
