A new Zitterbewegung velocity is identified from the quantum Liouville equation using out-of-phase components of the quantum geometric tensor; it resolves the position-shift paradox upon integration of semiclassical equations and connects to the minimum conductivity of massless Dirac fermions.
A symmetry-based method using field-reversal and angular dependence disentangles anisotropy and Berry curvature contributions to in-plane Hall responses, demonstrated on Fe3Sn.
First-principles calculations predict a topological magnetoelectric coupling α^zz up to 0.9 e²/2h in Co-intercalated NbS2 with layer-staggered scalar spin chirality, switchable to anomalous Hall effect by strain.
Interface-induced Rashba spin-orbit interaction, rather than strain, governs anomalous Hall conductivity in Ni heterostructures and enables continuous electric-field tuning.
