HartreeFock Ground State of the Composite Fermion Metal
Abstract
Within the HartreeFock approximation the ground state of the composite fermion metal is found. We observe that the singleparticle energy spectrum is dominated by the logarithmic interaction exchange term which leads to an infinite jump of the singleparticle exchange at the Fermi momentum. It is shown that the HartreeFock result brings no corrections to the RPA Fermi velocity.
