The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

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 …

We implemented the charge self-consistent combination of density-functional theory and
dynamical mean-field theory (DMFT) in two full-potential methods, the augmented plane …

The origin of the exceptionally strong superconductivity of cuprates remains a subject of
debate after more than two decades of investigation. Here we follow a new lead: The onset …

The study of quantum phase transitions that are not clearly associated with broken symmetry
is a major effort in condensed matter physics, particularly in regard to the problem of high …

Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy
(STM) have become indispensable tools in the study of correlated quantum materials. Both …

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
of antiferromagnetic order, unconventional superconductivity and quantum criticality due to …

This article overviews the development of heavy-fermion superconductivity, notably in such
rare-earth-based intermetallic compounds which behave as Kondo-lattice systems. Heavy …
