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

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 …

Quantum phase transitions arise in many-body systems because of competing interactions
that promote rivaling ground states. Recent years have seen the identification of continuous …

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 …

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

Suitable for researchers and graduate students in physics and material science," Physical
Acoustics in the Solid State" reviews the modern aspects in the field, including many …

Strongly correlated systems present fundamental challenges, especially in materials in
which electronic correlations cause a strong increase of the effective mass of the charge …

The origin of unconventional superconductivity, including high-temperature and heavy-
fermion superconductivity, is still a matter of controversy. Spin excitations instead of phonons …

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

Ce115 and related Ce compounds are particularly suited to detailed studies of the interplay
