## Description

- description: A fundamental requirement for quantum technologies is the ability to
    coherently control the interaction between electrons and photons. However, in
    many scenarios involving the interaction between light and matter, the exchange
    of linear or angular momentum between electrons and photons is not feasible, a
    condition known as the dipole approximation limit. An example of a case beyond
    this limit that has remained experimentally elusive is when the interplay between
    chiral electrons and vortex light is considered, where the orbital angular momentum
    of light can be transferred to electrons. Here we present a mechanism for such
    an orbital angular momentum transfer from optical vortex beams to electronic quantum
    Hall states. Specifically, we identify a robust contribution to the radial photocurrent,
    in an annular graphene sample within the quantum Hall regime, that depends on
    the vorticity of light. This phenomenon can be interpreted as an optical pumping
    scheme, where the angular momentum of photons is transferred to electrons, generating
    a radial current, and the current direction is determined by the vorticity of
    the light. Our findings offer fundamental insights into the optical probing and
    manipulation of quantum coherence, with wide-ranging implications for advancing
    quantum coherent optoelectronics.
