WebNov 18, 2024 · The orbital Hall effect describes the generation of the orbital current flowing in a perpendicular direction to an external electric field, analogous to the spin Hall effect. … WebSep 24, 2024 · Here, orbital information is encoded in coefficients , which can be controlled by external perturbations. For instance, a wave packet with and carries a finite orbital angular momentum (OAM) along the z -direction. Note that the coefficients behave as an "internal" degree of freedom of the wave packet, analogously to the case of spin.
