Query: Hartree-Fock ground state of the composite fermion metal   Within the Hartree-Fock approximation the ground state of the composite
fermion metal is found. We observe that the single-particle energy spectrum is
dominated by the logarithmic interaction exchange term which leads to an
infinite jump of the single-particle energy at the Fermi momentum. It is shown
that the Hartree-Fock result brings no corrections to the RPA Fermi velocity.
