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 …

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

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 …

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 …

An overview of quantum phase transitions (QPTs) in metallic ferromagnets, discussing both
experimental and theoretical aspects, is given. These QPTs can be classified with respect to …

'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …

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

In this article we review essential natures of superconductivity in strongly correlated electron
systems (SCES) from a universal point of view. First we summarize experimental results on …

Our present understanding of how the interactions between electrons affect the metallic state
has, for forty years, rested on the foundations of Landau's Fermi-liquid theory. It provides the …
