This article reviews odd-frequency (odd-ω) pairing with a focus on superconducting systems.
Since Berezinskii introduced the concept of odd-frequency order in 1974 it has been viewed …

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 …

NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

This book presents in a pedagogical yet complete way correlated systems in one dimension.
Recent progress in nanotechnology and material research have made one dimensional …

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 the early 1970s, Wilson developed the concept of a fully nonperturbative renormalization
group transformation. When applied to the Kondo problem, this numerical renormalization …

This review presents recent developments in the understanding of how impurities influence
the electronic states in the bulk properties of superconductors. The focus is on …

In recent years, quantum phase transitions have attracted the interest of both theorists and
experimentalists in condensed matter physics. These transitions, which are accessed at zero …

This article reviews the physics of multipolar interactions and multipolar order in f-electron
systems, using the actinide dioxides as a paradigm. In the past few years, these apparently …

The multipole moment is an established concept of electrons in solids. Entanglement of spin,
orbital, and sublattice degrees of freedom is described by the multipole moment, and …
