Self-consistent pseudopotentials in the thermodynamic limit. II. The state-dependent one-body field

We explore the concept of the pseudopotential, introduced in a previous paper, within the context of the exact boundary condition for a system of fermions interacting through a pair-wise, hard-core potential, in the thermodynamic limit. We discuss several Ansätze for the Lagrange multipliers that al...
