Dmitry Karlovets (ITMO) "A new tool for accelerator physics: LINAC with twisted electron beams"

Twisted quantum states of particles possess a vortex wave front structure and carry quantized angular momentum along the propagation direction. Such states have already been successfully realized for photons, as well as electrons, neutrons, and ions at nonrelativistic energies.

Relativistic twisted particles could become a unique new research tool in high-energy physics, opening up new possibilities for studying strong interactions at low energies, quantum measurements and entanglement, quantum tomography, proton spin structure, the production of spin-polarized beams, and other applications.

To implement them at accelerators, in addition to developing the theoretical foundations, it is necessary to develop and implement new technologies for generating, transporting, and detecting twisted beams, somewhat similar to approaches used in electron microscopy and quantum optics.

We will discuss how LINAC can become the world's first facility where technologies for working with relativistic twisted electrons will be systematically developed and refined, and we will also propose a number of unique experiments that are inaccessible using conventional particle beams.
