## Description

- description: Photons that acquire orbital angular momentum move in a helical path
    and are observed as a light ring. During helical motion, if a force is applied
    perpendicular to the direction of motion, an additional radial angular momentum
    is introduced, and alternate dark spots appear on the light ring. Here, a third,
    centrifugal angular momentum has been added by twisting the helical path further
    according to the three-step hierarchical assembly of helical organic nanowires.
    Attaining a third angular momentum is the theoretical limit for a photon. The
    additional angular momentum converts the dimensionless photon to a hollow spherical
    photon condensate with interactive dark regions. A stream of these photon condensates
    can interfere like a wave or disintegrate like matter, similar to the behavior
    of electrons.
