Fast Electrons Interacting with Chiral Matter: Mirror-Symmetry Breaking of Quantum Decoherence and Lateral Momentum Transfer

Photons experience mirror asymmetry of macroscopic chiral media, as in circular dichroism and polarization rotation, since left- right-handed polarizations differently couple with matter handedness. Conversely, free relativistic electrons vanishing orbital angular momentum have no handedness so the question arises whether they can sense chirality geometrically symmetric samples. In this paper, we show that breaks symmetry scattered electrons' quantum decoherence, even when incident electron wave function sample shape a common reflection plane. This is physically possible wave-function transverse smearing triggers sensitivity to spatial electromagnetic interaction sample, results from our nonperturbative analysis reduced density matrix, framework electrodynamics. Furthermore, prove also shows up distribution lateral momentum, orthogonal geometric plane, whose nonvanishing mean value reveals experiences mechanical entirely produced by chirality.
