QUANTUM MATTER SEMINAR

"Strange Metal Physics in Heavy Fermion Systems and beyond"

Professor Silke Buehler-Paschen, Professor of Physics, Physics, The Vienna University of Technology,

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. Its

full understanding 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, strongly suppressed shot noise, and a

quantum Fisher information analysis of inelastic neutron scattering data, which provides first evidence of high

multipartite entanglement in the strange metal state.
