Abstract: Plasmonic nanosystems are typically used in optical experiments to concentrate electromagnetic energy into sub-wavelength volumes. In this context, metal-dielectric-metal (MDM) nanosystems provide an attractive geometry for achieving strong field enhancement and mode confinement on a… read more here.

DOI: 10.1103/physrevlett.130.186901
Abstract: Polarizing electron beams using light is highly desirable but exceedingly challenging, as the approaches proposed in previous studies using free-space light usually require enormous laser intensities. Here, we propose the use of a transverse electric… read more here.
