We show that if the repulsive interaction extends to the contact regions, a strong increase of the conductance may occur, even for systems where one would expect to find a reduced conductance. An essential ingredient in our calculations is a momentum-space representation of the leads, which allows a high energy resolution. Further, we demonstrate that these results are independent of the high-energy cutoff and that the relevant scale is set by the Fermi velocity.Published version -- references correctedStrongly Correlated Electronstext
