  A derivation of the anomaly-induced transport phenomena---the chiral
magnetic/vortical effect---is revisited based on the imaginary-time formalism
of quantum field theory. Considering the simplest anomalous system composed of
a single Weyl fermion, we provide two derivations: perturbative (one-loop)
evaluation of the anomalous transport coefficient, and the anomaly matching for
the local thermodynamic functional.
