Abstract

We present a free energy functional for superfluid ³He in the presence of homogeneously distributed impurity disorder which extends the Ginzburg-Landau free energy functional to all temperatures. We use the new free energy functional to calculate the thermodynamic potential, entropy, heat capacity and density of states for the B-phase of superfluid ³He in homogeneous, isotropic aerogel.
