Propagation of shear stress in strongly interacting metallic Fermi liquids enhances transmission of terahertz radiation

Abstract A highlight of Fermi-liquid phenomenology, as explored in neutral $$^3$$ 3 He, is the observation that in the collisionless regime shear stress propagates as if one is dealing with the transverse phonon of a solid. The existence of this “transverse zero sound” requires that the quasiparticl...
