Owing to their large relatively thermal conductivity, peculiar, non-hydrodynamic features are
expected to characterize the acoustic-like excitations observed in liquid metals. We report
here an experimental study of collective modes in molten nickel, a case of exceptional
geophysical interest for its relevance in Earth interior science. Our result shed light on
previously reported contrasting evidences: in the explored energy-momentum region no
deviation from the generalized hydrodynamic picture describing non conductive fluids are …

We report here an experimental study of collective modes in molten nickel, a case of exceptional geophysical interest for its relevance in Earth interior science. Our result shed light on previously reported contrasting evidences: in the explored energy-momentum region no deviation from the generalized hydrodynamic picture describing non conductive fluids are observed. Implications for high frequency transport properties in metallic fluids are discussed.
