Query: Kondo resonance for orbitally degenerate systems   Formation of the Kondo state in general two-band Anderson model has been
investigated within the numerical renormalization group (NRG) calculations. The
Abrikosov-Suhl resonance is essentially asymmetric for the model with one
electron per impurity (quarter filling case) in contrast with the one-band
case. An external magnetic (pseudo-magnetic) field breaking spin (orbital)
degeneracy leads to asymmetric splitting and essential broadening of the
many-body resonance. Unlike the standard Anderson model, the ``spin up'' Kondo
peak is pinned against the Fermi level, but not suppressed by magnetic field.
