We show that Weyl semimetals exhibit a mixed axial-torsional anomaly in thepresence of axial torsion, a concept exclusive of these materials with no knownnatural fundamental interpretation in terms of the geometry of spacetime. Thisanomaly implies a nonconservation of the axial current---the difference incurrent of left- and right-handed chiral fermions---when the torsion of thespacetime in which the Weyl fermions move couples with opposite sign todifferent chiralities. The anomaly is activated by driving transverse soundwaves through a Weyl semimetal with a spatially varying tilted dispersion,which can be engineered by applying strain. This leads to sizable alternatingcurrent in presence of a magnetic field that provides a clear-cut experimentalsignature of our predictions.
