  We study equilibrium transport properties of massless Dirac fermions at
finite temperature and chemical potential in spacetime accompanied by torsion,
which in four dimensions couples with Dirac fermions as an axial gauge field.
In particular, we compute the current density at the linear order in the
torsion as well as in an external magnetic field with the Pauli-Villars
regularization, finding that an equilibrium current akin to the chiral magnetic
current is locally induced. Such torsion can be realized in condensed matter
systems along a screw dislocation line, around which localized and extended
current distributions are predicted so as to be relevant to Dirac and Weyl
semimetals. Furthermore, we compute the current density at the linear order in
the torsion as well as in a Weyl node separation, which turns out to vanish in
spite of being allowed from the symmetry perspective. Contrasts of our findings
with torsion-induced currents from previous work are also discussed.
