Planar magnetotransport yields distinct quantum-geometric fingerprints of d-, g-, and i-wave altermagnetic order via magnetic-field-induced Berry curvature and quantum metric susceptibilities.
Nonlinear anomalous Hall response computed from the Berry curvature dipole in strained moiré dice lattices reverses sign across topological phase boundaries, providing a probe for valley-specific topology far from charge neutrality.
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.
