... These new forms of total angular momentum differ from the standard one, but nonetheless have the physical properties we expect. The established method for measuring an optical angular momentum, be it L, S, or J1 = L + S, involves rotating the beams traversing a Mach-Zehnder interferometer (6). This ...
