Since the discovery by Steglich et al.(1979) of superconductivity in the high-effective-mass
(∼ 200 me) electrons in Ce Cu 2 Si 2, the search for and characterization of such" heavy …

The heavy-fermion metal CeCu 2 Si 2 was the first discovered unconventional, non-phonon-
mediated superconductor and, for a long time, was believed to exhibit single-band d-wave …

Correct descriptions of the electronic structures of dilute alloys of 3d and 4f elements in
simple metals, and explanations of their properties in terms of such descriptions, challenged …

In a conventional superconductor, the binding of electrons into the paired states that
collectively carry the supercurrent is mediated by phonons—vibrations of the crystal lattice …

We study the low-temperature Anderson lattice Hamiltonian via an ''auxiliary-boson''1/N
expansion that generalizes to a lattice an approach previously used to study one Anderson …

This review considers the experimental and theoretical studies of concentrated Kondo
