  Within random matrix theory for quantum dots, both the dot's one-particle
eigenlevels and the dot-lead couplings are statistically distributed. While the
effect of the latter on the conductance is obvious and has been taken into
account in the literature, the statistical distribution of the one-particle
eigenlevels is generally replaced by a picket-fence spectrum. Here we take the
random matrix theory eigenlevel distribution explicitly into account and
observe significant deviations in the conductance distribution and
magnetoconductance of closed quantum dots at experimentally relevant
temperatures.
