The electric magnetochiral anisotropy is a nonreciprocal phenomenon accessible via second harmonic transport in noncentrosymmetric, time-reversal invariant materials, in which the rectification of current, $\mathbf{I}$, can be controlled by an external magnetic field, $\mathbf{B}$. Quantum geometry,… [Phys. Rev. Lett. 135, 106602] Published Tue Sep 02, 2025
