Spinning radiation from a topological insulator

Spinning radiation from a topological insulator

We show that thermal radiation from a topological insulator carries a nonzero average spin angular momentum. This effect can offer an approach to the generation of elliptically polarized thermal emission without the need of complicated surface structuring of the source.
