Ti and Changing PE Spin Polarization

Caption

Incident light that's p-polarized (upper left) produces photoelectrons consistent with the usual picture of spin polarization in a topological insulator's surface, but changing the polarization of the incident light also changes the spin polarization of the photoelectrons.
