A decomposition of light's spin angular momentum density
Alex J. Vernon, Sebastian Golat, Claire Rigouzzo +2
Light carries intrinsic spin angular momentum (SAM) when the electric or magnetic field vector rotates over time. A familiar vector equation calculates the direction of light's SAM…

3D Zeros in Electromagnetic Fields
Alex J. Vernon, Mark R. Dennis, Francisco J. Rodríguez-Fortuño
We present a study of 3D electromagnetic field zeros, uncovering their remarkable characteristic features and propose a classifying framework. These are a special case of general d…
