  We calculate and resolve with unprecedented detail the local density of
states (DOS) and momentum-dependent spectral functions at zero temperature of
one of the key models for strongly correlated electron materials, the
degenerate two-orbital Kanamori-Hubbard model, by means of a highly optimized
Dynamical Mean Field Theory which uses the Density Matrix Renormalization Group
as the impurity solver. When the system is hole doped, and in the presence of a
finite interorbital Coulomb interaction we find the emergence of a novel
holon-doublon in-gap subband which is split by the Hund's coupling. We also
observe new interesting features in the DOS like the splitting of the lower
Hubbard band into a coherent narrowly dispersing peak around the Fermi energy,
and another subband which evolves with the chemical potential. We characterize
the main transitions giving rise to each subband by calculating the response
functions of specific projected operators and comparing with the energies in
the atomic limit, obtaining excellent agreement. The detailed results for the
spectral functions found in this work pave the way to study with great
precision the microscopic quantum behavior in correlated materials.
