We propose a minimal model for realizing true chiral symmetry breaking on a magnetized surface, with a crucial role played by the tilt angle of the molecular dipole with respect to the surface. For non-zero tilting, we show that the Hall response exhibits clear signatures of chirality-induced effects, in both charge- and spin-resolved observables. Concerning the former, tilted enantiomers produce asymmetric Hall conductances and, even more remarkably, the persistence of this feature in the absence of spin–orbit coupling (SOC) signals how the enantiospecific charge response results from electron scattering off the molecular potential. Concerning spin-resolved observables where SOC plays a relevant role, we reveal that chiral symmetry breaking is crucial in enabling spin-flipping processes. https://research-explorer.ista.ac.at/download/19880/19881/2025_JourChemicalPhysics_AlHyder.pdf application/pdfno https://creativecommons.org/licenses/by/4.0/ AIP Publishing2025 eng 0021-9606 1089-7690 2503.14124 40526561 00151287290001010.1063/5.0271155 16223 Al Hyder R, Lemeshko M, Cappellaro A.
