Surface Specific Heat of ${}^3$He and Andreev Bound States

Abstract

High resolution measurements of the specific heat of liquid ${}^3$He in the presence of a silver surface have been performed at temperatures near the superfluid transition in the pressure range of 1 to 29 bar. The surface contribution to the heat capacity is identified with Andreev bound states of ${}^3$He quasiparticles that have a range of half a coherence length.
