  • Recently, there has been great interest in studying plasmons in strange metals characterized by linear-in-temperature electrical resistivity. Schultz et al. report an EELS in transmission study of plasmons in Sr2RuO4, revealing unrenormalized behavior explained by resilient quasi-particles at high plasmon energy.

  • The authors present resonant inelastic x-ray scattering measurements of Sr2RuO4 in the normal Fermi-liquid state. They find that spin excitations are confined below 200 meV, while orbital fluctuations appear only at higher energies. This separation of energy scales is a hallmark of Hund’s-rule-induced electron correlations.
