Query: Non-Crossing Approximation Study of Multi-Orbital Kondo Effect in
  Quantum Dot Systems   We study the three-orbital Kondo effect in quantum dot (QD) systems by
applying the non-crossing approximation to the three-orbital Anderson impurity
model. By investigating the tunneling conductance through a QD, we show that
the competition between the Hund-coupling and the orbital level-splitting gives
rise to characteristic behavior in transport properties. It is found that the
Hund-coupling becomes more important in the three-orbital case than in the
two-orbital case. We also show that the enhancement of Kondo temperature due to
the singlet-triplet mechanism suggested for the two-orbital model tends to be
suppressed by the existence of the third orbital.
