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 …

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

We discuss non-Fermi liquid and quantum critical behaviour in heavy-fermion materials,
focusing on the mechanism by which the electron mass appears to diverge at the quantum …

The idea of superconductivity without the mediating role of lattice vibrations (phonons) has a
long history. It was realized soon after the publication of the Bardeen–Cooper–Schrieffer …

Only a few metallic phases have been identified in pure crystalline materials. These include
normal, ferromagnetic and antiferromagnetic metals, systems with spin and charge density …

In this review, we summarize the present status of theories of the spin fluctuation (SF)
mechanism in explaining anomalous or non-Fermi liquid behaviours and unconventional …

Over the past 35 years, research on unconventional superconductivity in heavy-fermion
systems has evolved from the surprising observations of unprecedented superconducting …

Although strongly correlated f-electron systems are well known as reservoirs for quantum
phenomena, a persistent challenge is to design specific states. What is often missing are …
