Currently, Weyl semimetals (WSMs) are drawing great interest as a new topological
nontrivial phase. When most of the studies concentrated on the clean host WSMs,
it is expected that the dirty WSM system would present rich physics due to the
interplay between the WSM states and the impurities embedded inside these
materials. We investigate theoretically the change of local density of states in
three-dimensional Dirac and Weyl bulk states scattered off a quantum impurity. It
is found that the quantum impurity scattering can create nodal resonance and
Kondo peak/dip in the host bulk states, remarkably modifying the pristine
spectrum structure. Moreover, the joint effect of the separation of Weyl nodes
and the Friedel interference oscillation causes the unique battering feature. We
in detail an- alyze the different contribution from the intra- and inter-node
scattering processes and present various scenarios as a consequence of
competition between them. Importantly, these behaviors are sensitive
significantly to the displacement of Weyl nodes in energy or momentum, from which
the distinctive fingerprints can be extracted to identify various semimetal
materials experimentally by employing the scanning tunneling microscope.
