Strongly correlated electron systems at the border of magnetism are of active current interest, particularly because the accompanying quantum criticality provides a route towards both strange‐metal non‐Fermi liquid behavior and unconventional superconductivity. Among the many important questions is whether the magnetism acts simply as a source of fluctuations in the textbook Landau framework, or instead serves as a proxy for some unexpected new physics. We put into this general context the… 
Exploring heavy fermions from macroscopic to microscopic length scales
Strongly correlated systems present fundamental challenges, especially in materials in which electronic correlations cause a strong increase of the effective mass of the charge carriers. Heavy
Foundations of heavy-fermion superconductivity: lattice Kondo effect and Mott physics
TLDR
This article overviews the development of heavy-fermion superconductivity, notably in such rare-earth-based intermetallic compounds which behave as Kondo-lattice systems, and concludes for YbRh2Si2, the breakdown of the Kondo effect concurring with the AF instability gives rise to an abrupt change of the Fermi surface.
Global phase diagram and momentum distribution of single-particle excitations in Kondo insulators
Kondo insulators are emerging as a simplified setting to study both magnetic and insulator-to-metal quantum phase transitions. Here, we study the half-filled Anderson lattice model defined on a
Are Heavy Fermion Strange Metals Planckian?
Strange metal behavior refers to a linear temperature dependence of the electrical resistivity that is not due to electron–phonon scattering. It is seen in numerous strongly correlated electron
Kondo Destruction and Quantum Criticality in Kondo Lattice Systems
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 leads to quantum
Weyl–Kondo semimetal in heavy-fermion systems
TLDR
Theoretical work on a strongly correlated lattice model is reported to demonstrate the emergence of a Weyl–Kondo semimetal phase in a periodic Anderson model on a noncentrosymmetric lattice that is realized in a recently discovered heavy-fermion compound.
Quantum phases driven by strong correlations
It has long been thought that strongly correlated systems are adiabatically connected to their non-interacting counterpart. Recent developments have highlighted the fallacy of this traditional notion
Physical Properties of CeCuAs2
Kondo insulators and heavy fermion metals are strongly correlated materials that have been investigated for more than 40 years. In these materials, the hybridization between conduction bands and

Quantum criticality and global phase diagram of magnetic heavy fermions
Quantum criticality describes the collective fluctuations of matter undergoing a second‐order phase transition at zero temperature. It is being discussed in a number of strongly correlated electron
Heavy Fermions and Quantum Phase Transitions
TLDR
Recent years have seen the identification of continuous quantum phase transitions, or quantum critical points, in a host of antiferromagnetic heavy-fermion compounds and quantum criticality has provided fresh insights into the electronic, magnetic, and superconducting properties of the heavy-FERmion metals.
Frustration and the Kondo Effect in Heavy Fermion Materials
The observation of a separation between the antiferromagnetic phase boundary and the small-large Fermi surface transition in recent experiments has led to the proposal that frustration is an

We discuss the general theoretical arguments advanced earlier for the T=0 global phase diagram of antiferromagnetic Kondo lattice systems, distinguishing between the established and the conjectured.

Quantum phase transitions have captured the interest of a large community in condensed-matter and atom physics research. The common feature of these very different material classes lies in the fact
Hall-effect evolution across a heavy-fermion quantum critical point
TLDR
Measurements of the low-temperature Hall coefficient (RH)—a measure of the Fermi surface volume—in the heavy-fermion metal YbRh2Si2 upon field-tuning it from an antiferromagnetic to a paramagnetic state are reported.
Locally critical quantum phase transitions in strongly correlated metals
TLDR
The theoretical finding of a locally critical quantum phase transition in a model of heavy fermions is reported, and local criticality is proposed to be a phenomenon of general relevance to strongly correlated metals.

A cubic heavy-fermion material is identified as exhibiting a field-induced quantum phase transition, and it is shown how the material can be used to explore one extreme of the dimensionality axis, leading to a materials-based global phase diagram.
