Query: The Addition Spectrum and Koopmans' Theorem for Disordered Quantum Dots   We investigate the addition spectrum of disordered quantum dots containing
spinless interacting fermions using the self-consistent Hartree-Fock
approximation. We concentrate on the regime r_s >~1, with finite dimensionless
conductance g. We find that in this approximation the peak spacing fluctuations
do not scale with the mean single particle level spacing for either Coulomb or
nearest neighbour interactions when r_s >~1. We also show that Koopmans'
approximation to the addition spectrum can lead to errors that are of order the
mean level spacing or larger, both in the mean addition spectrum peak spacings,
and in the peak spacing fluctuations.
