Tunneling exponents in realistic quantum wires using the mean field approximation

It is demonstrated that the charge Tomonaga-Luttinger parameter $K_ρ$ of quantum wires can be estimated accurately using the Hartree-Fock approximation if carried out self consistently. The dependence of $K_ρ$ on the carrier density distinguishes different regimes of importance of correlations.
