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

This review article is devoted to the interplay between frustrated magnetism and quantum
critical phenomena, covering both theoretical concepts and ideas as well as recent …

Van Hove points are special points in the energy dispersion, where the density of states
exhibits analytic singularities. When a Van Hove point is close to the Fermi level, tendencies …

First-principles density functional theory calculations are performed to understand the
electronic structure and interaction parameters for recently discovered superconducting …

Twisted trilayer graphene (TTG) has recently emerged experimentally as a fascinating
playground to study correlated and exotic superconducting phases. We have found that TTG …

CeRh 2 As 2, a nonsymmorphic heavy fermion material, was recently reported to host a
remarkable temperature versus z-axis magnetic-field phase diagram with two …

Motivated by the experimental identification of a higher-order Van Hove singularity (VHS) in
AV 3 Sb 5 kagome metals, we study electronic instabilities of two-dimensional lattice models …

Bicritical points, at which two distinct symmetry-broken phases become simultaneously
unstable, are typical for spin-flop metamagnetism. Interestingly, the heavy-fermion …

A fundamental challenge to our current understanding of metals is the observation of
qualitative departures from Fermi liquid behavior. The standard view attributes such non …

Understanding the strange metallic behavior that develops at the brink of localization in
quantum materials requires probing the underlying electronic charge dynamics. Using …
