CNQM2023: Silke Bühler-Paschen - Strange metal behavior in heavy fermion compounds and beyond

Silke Bühler-Paschen (TU Wien) - Strange metal behavior in heavy fermion compounds and beyond Strange metal behavior – best known as a linear-in-temperature electrical resistivity out of which unconventional superconductivity nucleates – is ubiquitous in many classes of strongly correlated electron systems, and has recently also been observed in new flat band platforms. A unified understanding is in high demand. The heavy fermion compound YbRh2Si2 is a particularly versatile model system for studying this physics. I will present its salient features, including the dynamical scaling of the optical conductivity, its superconductivity at ultralow temperatures, and its strongly suppressed shot noise. I will also discuss evidence for (some of) these features in other material’s classes, the topic of Planckian scattering, and how insights gained from all these experimental results may boost the theoretical understanding.
