Query: Dynamical correlation functions and the related physical effects in
  three-dimensional Weyl/Dirac semimetals   We present a unified derivation of the dynamical correlation functions
including density-density, density-current and current-current, of
three-dimensional Weyl/Dirac semimetals by use of the Passarino-Veltman
reduction scheme at zero temperature. The generalized Kramers-Kronig relations
with arbitrary order of subtraction are established to verify these correlation
functions. Our results lead to the exact chiral magnetic conductivity and
directly recover the previous ones in several limits. We also investigate the
magnetic susceptibilities, the orbital magnetization and briefly discuss the
impact of electron interactions on these physical quantities within the random
phase approximation. Our work could provide a starting point for the
investigation of the nonlocal transport and optical properties due to the
higher-order spatial dispersion in three-dimensional Weyl/Dirac semimetals.
