Strange metal behavior – best known as a linear-in-temperature electrical resistivity at low temperatures instead of the normal Fermi liquid square-in-temperature one – occurs across many classes of quantum materials [1,2]. As the parent state of high-temperature superconductivity, it is of broad interest. Its full understanding, however, is a major challenge. Heavy fermion compounds are particularly versatile model materials for studying this physics: they are comparatively simple, clean, and highly tunable, and several characteristics beyond linear-in-temperature resistivity have already been identified. I will give an overview and highlight recent results, including dynamical scaling of the terahertz conductivity [3], strongly suppressed shot noise [4], and a quantum Fisher information analysis of inelastic neutron scattering data [5].
