A relatively new class of materials has been found in which the basic assumption of Landau
Fermi-liquid theory—that at low energies the electrons in a metal should behave essentially …

This review discusses the heavy-electron compounds and related materials from the
perspective of their electrodynamic response. The investigation of the electrodynamic …

The specific heat C and electrical resistivity ρ of the heavy-fermion alloy CeCu 5.9 Au 0.1
exhibit non-Fermi-liquid behavior well below 1 K, ie, C/T∝-ln (T/T 0) and ρ= ρ 0+ A'T, over …

Systematic deviations from standard Fermi-liquid behaviour have been widely observed and
documented in several classes of strongly correlated metals. For many of these systems …

We have determined the magnetic response S (ω) of UCu 5− x Pd x (x= 1, 1.5) for
temperatures T ranging from 12 to 300 K and energy transfers ω from 0.5 to 200 meV. S (ω) …

Strong inhomogeneous broadening of the copper NMR line in UCu 5− x Pd x, x= 1.0 and
1.5, indicates that spin susceptibility disorder contributes to the non-Fermi-liquid behavior of …

We show how a model of disordered Anderson lattices can account for many non-Fermi-
liquid features observed in some Kondo alloys. Because of the exponential nature of the …

In heavy-fermion systems with 4f or 5f atoms (such as Ce or U) the competition between the
on-site moment compensation by the Kondo effect and the long-range RKKY interaction …

We present a general model of disorder in Kondo alloys that, under certain conditions, leads
to non-Fermi-liquid behaviour. The central underlying idea is the presence of a distribution …

We review the theory of interacting Fermi systems whose low-energy physics is dominated
by forward scattering, that is scattering processes generated by effective interactions with …
