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

This Colloquium reviews the 25 year quest to understand the continuous (second-order),
mean-field-like phase transition occurring at 17.5 K in URu 2 Si 2. About ten years ago, the …

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 …

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 …

Spin-triplet superconductors are of extensive current interest because they can host
topological state and Majorana fermions important for quantum computation. The uranium …

A second-order phase transition is characterized by spontaneous symmetry breaking. The
nature of the broken symmetry in the so-called “hidden-order” phase transition in the heavy …

Within a Kondo lattice, the strong hybridization between electrons localized in real space (r-
space) and those delocalized in momentum-space (k-space) generates exotic electronic …

The author attempts to give a comprehensive discussion of studies performed with the
positive-muon spin rotation and relaxation technique (also known as the μSR technique) on …

This topical review describes the multitude of unconventional behaviors in the hidden order,
heavy fermion, antiferromagnetic and superconducting phases of the intermetallic …

Exotic electronic states resulting from entangled spin and orbital degrees of freedom are
hallmarks of strongly correlated f-electron systems. A spectacular example is the so-called …
