Abstract
Quantum states with finite scalar spin chirality carry an orbital magnetic moment that has eluded direct measurement. We show that a local drive breaks the cyclic symmetry and activates chirality-changing transitions. We propose two complementary probes: direct chirality resonance and chirality-resolved spin resonance. Lindblad simulations demonstrate their feasibility in locally addressable spin platforms, including scanning tunneling microscopy, silicon donors, and quantum dots.
