Abstract

The measurement of the spin angular momentum of circularly polarized light by Beth [Phys. Rev. 50, 115 (1936)] can be explained by using a microscopic torque density. However, the experiment does not resolve the space- and time-dependent evolution of the spin density of light and the wave plate and the covariant form of the microscopic torque density. Here we focus on the covariant description of the helicity, spin, and torque densities of light in materials using the chiral-stress-energy-momentum tensor. We also perform simulations of Gaussian light pulses in quarter-wave-plate geometries made of birefringent and dielectric materials.
