Abstract

The coefficients in the expansion of the free energy and supercurrents in gradients of the order parameter are calculated from the microscopic Hamiltonian for all temperatures, first for a gas model and then including Fermi liquid corrections. This provides the basis for a simple discussion of the supercurrents and collective modes. The magnitude of the intrinsic orbital angular momentum in the Anderson-Brinkman-Morel phase is calculated, and found to beTc/EF smaller than previous estimates.
