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 classical, thermally driven transition in the dipolar-coupled Ising ferromagnet LiHo F 4 (T
c= 1.53 K) can be converted into a quantum transition driven by a transverse magnetic field …

We study the doping of a Mott insulator in the presence of quenched frustrating disorder in
the magnitude and sign of the magnetic exchange. Two quite different doping regimes δ< δ …

We measured the specific heat and resistivity of heavy fermion C e C o I n 5 between the
superconducting critical field H c 2= 5 T and 9 T, with the field in the [001] direction, and at …

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 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 …

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 study the competition between the Kondo effect and Ruderman-Kittel-Kasuya-Yosida
interactions near the zero-temperature quantum critical point of an Ising-like metallic spin …

We report a S 29 i NMR study on aligned single crystals of Y b R h 2 S i 2 which shows
behavior characteristic of a quantum critical point (QCP: TN→ 0). The Knight shift K and the …
