The authors derive and analyze the second-order electric-field contributions to current in topological Dirac semimetals with parallel magnetic field, focusing on Berry curvature dipole and field-induced terms, and propose experimental tests via anomalous Hall resistivity in specific materials.
Nonlinear thermal and thermoelectric responses are shown to encode quantum geometry and satisfy relations parallel to the Wiedemann-Franz and Mott laws in systems with broken symmetries.
