Viscoelasticity in normal He as a consequence of the Landau theory of normal Fermi liquids

arXiv:cond-mat/0304639

Abstract

We show that a viscoelastic dispersion relation for shear waves in normal He at low temperatures follows directly from the Landau theory of normal Fermi liquids. This theoretical result is in accord with the experimental observations of propagating high frequency shear waves that identify normal He as a viscoelastic substance.
