Both classical and quantum waves can form vortices: entities with helical phase fronts and
circulating current densities. These features determine the intrinsic orbital angular …

The recent prediction and subsequent creation of electron vortex beams in a number of
laboratories occurred after almost 20 years had elapsed since the recognition of the physical …

With the development of various emerging technologies, the capacity of current wireless
communication system is gradually saturated, and terahertz (THz) and orbital angular …

Dielectric laser accelerators (DLAs) hold great promise for producing economic and
compact on-chip radiation sources. On-chip DLAs benefit from fabrication capabilities of the …

The electron vortex beam (EVB)-carrying quantized orbital angular momentum (OAM) plays
an essential role in a series of fundamental research. However, the radius of the transverse …

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 …

In this paper, an alternative kind of electron circle butterfly vortex beam (ECBVB) based on
the butterfly catastrophe is introduced, and its propagation characteristics in free space and …
