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

Considerable efforts have been made in recent years to theoretically understand quantum
phase transitions in Kondo lattice systems. A particular focus is on Kondo destruction, which …

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

Classification and understanding of quantum phase transitions and critical phenomena in
itinerant electron systems are outstanding questions in quantum materials research. Recent …

Dimensionality plays an essential role in determining the anomalous non-Fermi liquid
properties in heavy fermion systems. So far most heavy fermion compounds are quasi-two …

Notable non-Fermi liquid and quantum critical behaviors are observed in rare-earth metallic
systems with non-Kramers local moments supporting a number of different multipolar …

We propose a phenomenological framework for three classes of Kondo lattice materials that
incorporates the interplay between the fluctuations associated with the antiferromagnetic …

In this paper the low-temperature properties of two isostructural canonical heavy-fermion
compounds are contrasted with regards to the interplay between antiferromagnetic (AF) …

In the first part of this article, I briefly review early research activities concerning strongly
correlated electron systems, beginning with the discovery of superconductivity and the first …

The tetragonal heavy-fermion metal YbRh2Si2 orders antiferromagnetically at TN= 70 mK
and exhibits an unconventional quantum critical point (QCP) of Kondo-destroying type at …
