Electrons with a twist: a new probe of electromagnetic interactions
Dr. Igor Ivanov (CFTP, Instituto Superior Tecnico, Universidade de Lisboa, Portugal)

I will give an introduction to the topic of vortex electron beams, which emerged a few years ago and has already found applications.
Vortex electron beams are freely propagating electrons with helical wave-fronts and carry intrinsic orbital angular momentum.
These features modify the electron behavior in external fields, as well as radiation and scattering processes, offering new insights into electromagnetic interactions.
