Pressure has long been recognized as a fundamental thermodynamic variable but its
application was previously limited by the available pressure vessels and probes. The …

This review discusses instabilities of the Fermi-liquid state of conduction electrons in metals
with particular emphasis on magnetic quantum critical points. Both existing theoretical …

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 …

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 …

Quantum criticality describes the collective fluctuations of matter undergoing a second-order
phase transition at zero temperature. Heavy-fermion metals have in recent years emerged …

The absence of simple examples of superconductivity adjoining itinerant-electron
ferromagnetism in the phase diagram has for many years cast doubt on the validity of …

C e P t 3 S i is a novel heavy fermion superconductor, crystallizing in the C e P t 3 B structure
as a tetragonally distorted low symmetry variant of the A u C u 3 structure type. C e P t 3 S i …

Intermetallic compounds containing f-electron elements display a wealth of superconducting
phases, which are prime candidates for unconventional pairing with complex order …

The ordinary single-channel Kondo model consists of one or more spin-½ local moments
interacting antiferromagnetically with conduction electrons in a metal. This model has …

Low temperature specific heat and thermal conductivity measurements on the ambient
pressure heavy fermion superconductors CeIrIn 5 and CeCoIn 5 reveal power law …
