| Outline of Final Research Achievements |
We have developed an electron gun that generates structured electron beams having a specific amplitude and phase distribution by illuminating a semiconductor photocathode with structured light. An optical system that generates structured light with a specific intensity distribution was constructed using a spatial phase modulator and mounted on an electron microscope. It was confirmed that electron beams are generated by the structured light generated by the present optical system. We also conducted an intensity interference experiment using spin-polarized electrons, and found that electron beams with spin polarizations of ± 80% show anti-bunching phenomena which is not observed by electron beams with a spin polarization of 0%. In addition, we constructed a theory that describes the quantum interference effect and the breaking of Bell's inequality, and elucidated the mechanism by which weak values occur.
