Topological piezoelectric effect and parity anomaly in nodal line semimetals

Lattice deformations act on the low-energy excitations of Dirac materials as effective axial vector fields. This allows one to directly detect quantum anomalies of Dirac materials via the response to axial gauge fields. We investigate the parity anomaly in Dirac nodal line semimetals induced by latt...
