Query: Type-II Dirac states in full Heusler compounds XInPd2 (X = Ti, Zr and
  Hf)   We predict three full Heusler compounds XInPd2 (X = Zr, Hf and Ti) to be
potential candidates for type-II Dirac semimetals. The crystal symmetry of
these compounds have appropriate chemical environment with a unique interplay
of inversion, time reversal and mirror symmetry. These symmetries help to give
six pairs of type-II Dirac nodes on the C_4 rotation axis, closely located
at/near the Fermi level. Using first principle calculations, symmetry arguments
and crystal field splitting analysis, we illustrate the occurrence of such
Dirac nodes in these compounds. Bulk Fermi surfaces have been studied to
understand the Lorentz symmetry breaking and Lifshitz transition (LT) of Fermi
surfaces. Bulk nodes are projected on the (001) and (111) surfaces which form
the surface Fermi arcs, that can further be detected by probes such as angle
resolved photo-emission and scanning tunneling spectroscopy. By analyzing the
evolution of arcs with changing chemical potential, we prove the fragile nature
and the absence of topological protection of the Dirac arcs. Our predicted
compounds overcome the limitations of the previously reported PtTe2 class of
compounds.
