Order parameter of superfluidB3near surfaces

The order parameter of superfluid ${}_{}{}^3{}_{}{}^{}\mathit{B}$ is calculated near surfaces with the quasiclassical theory and a thin-dirty-layer surface-scattering model. The surface structures depend on the temperature, the surface roughness, the Fermi-liquid parameters, and the mass superflow tangential to the surface. All these are studied with special emphasis on the roughness and the superflow. A numerical technique of solving the quasiclassical equations is discussed.
