We show how the spin-orbit interaction of light in systems with non-circular symmetry changes optical angular momentum conservation, or even completely breaks it. We demonstrate our claims through phase-resolved near-field measurements and optical force calculations.

We measure the second-order coherence function g(2) for X-ray-driven light emission (scintillation), observing that it is bunched (g(2) > 1), and can achieve extreme bunching values (g(2)~97) in perovskite nano-crystals.

We present a novel method to shape single-electron wavepackets via their interaction with tunable plasmonic fields. We further demonstrate the first instance of electron diffraction from a standing electromagnetic surface wave - a plasmonic Kapitza-Dirac effect.
