SYSTEMS AND METHODS FOR ASSEMBLING ELECTRON SPIN AND CHARGE TO POSSESS PROPERTIES OF A MAGNETIC MONOPOLE

Described herein are systems and methods for assembling electron spin and charge to possess one or more properties of a magnetic monopole. Example systems can include a laser configured to generate a light beam with a first spin and/or a first orbital angular momentum, and a surface including a coupling structure having a geometrical charge. When exposed to the light beam, the surface is configured to enable excitations of surface plasmon polariton field waves at metal-dielectric interfaces of the coupling structure to generate a plasmonic field. The surface can be configured to focus the plasmonic field to form a plasmonic vortex, in which plasmonic spin-orbit coupling between a total spin and a total orbital angular momentum forms a topological spin texture that is homotopic to that of a magnetic monopole.
