## Abstract

Chirality-induced orbital-angular-momentum selectivity
(CIOAMS)
in electron transmission and scattering processes is investigated.
Polarization of the OAM of an electron traversing chiral media is
first studied via electronic wavepacket propagation using the time-dependent
Schrödinger equation. Next, spatial resolution of wavepackets
carrying opposite OAM, following scattering from a corrugated surface
is demonstrated. This suggests that OAM may play a significant role
in the mechanisms underlying chirality-induced spin selectivity, measured
for electrons crossing chiral media in setups involving Mott polarimetry.
Our results highlight the potential to exploit CIOAMS in innovative
emerging quantum technologies.
