MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less ...

Abstract: Spin angular momentum is a fundamental property of the propagating optical waves. In this work, we reveal a possibility of the continuous transition from the transverse spin angular momentum ...

Or one might employ circularly polarized light to selectively influence ... Furthermore, coupling between orbital angular momentum and spin could allow integration into existing spintronics ...

Abstract: This letter presents a triple-beam and triple-mode orbital angular momentum (OAM) generating metasurface ... 2 and 1 in three directions. Linearly and circularly polarized OAM beams can be ...

Our results indicate that this phenomenon can be attributed to the formation of photon-spin-dependent lattice modes when these arrays interact with circularly polarized light. In the metasurfaces ...
