Momentum transfer between 3He quasiparticles and surface VIA 4He boundary layer

In this paper a model of 3He liquid layer on an oscillating substrate with a thin superfluid 4He film as a boundary layer is considered. The complex surface impedance is calculated using the transmission line theory. The slip boundary condition and the vortex motion are taken into account to compute...

Description
Summary:In this paper a model of 3He liquid layer on an oscillating substrate with a thin superfluid 4He film as a boundary layer is considered. The complex surface impedance is calculated using the transmission line theory. The slip boundary condition and the vortex motion are taken into account to compute the momentum exchange between 3He and the solid surface. The calculated values are compared with experiments.
