Collision Drag Effect on Two-Fluid Hydrodynamics of Superfluid 3He in Aerogel

M. Miura, S. Higashitani, M. Yamamoto +1

Sound propagation in superfluid ${}^3$He in aerogel is studied on the basis of a two-fluid model taking into account the effect by the drag force due to collisions between ${}^3$He-qua…
