Query: Non-linear magneto-transport through small quantum dots at strong
  intra-dot correlations   Nonlinear transport through a quantum dot is studied in the limit of weak and
strong intra-dot Coulomb interaction. For the latter regime the nonequilibrium
self-consistent mean field equations for energies and spectral weights of
one-electron transitions are formulated. The increase of the bias-voltage
window leads to a strong deviation from Gibbs statistics: the populations of
states involved into a tunnelling are equalizing in this limit even at low
temperature. For a symmetric coupling of a quantum dot to two leads we provide
simple analytical relations between heights of the current steps and degeneracy
of a spectrum in a two-dimensional parabolic dot in a perpendicular magnetic
field in the both regimes.
