Fringe field induced spin-OAM mixing of twisted electrons
S. V. Gatalina, S. S. Baturin
We study spin effects in twisted-electron propagation through the entrance or exit region of an axially symmetric magnetic coil. Starting from the Foldy-Wouthuysen reduction of the…
Comment on "Angular momentum dynamics of vortex particles in accelerators''
S. S. Baturin
We comment on Ref.[D. Karlovets, D. Grosman, and I. Pavlov, Phys. Rev. Lett. 136, 085002 (2026)], which proposes a BMT-like equation for the mean kinetic orbital angular momentum (…
Tennis-racket instability of twisted electrons
S. S. Baturin
We demonstrate that a weak nonlinear magnetic entrance edge induces a tennis-racket (Dzhanibekov) instability in the shell-resolved orbital pseudospin dynamics of twisted electrons…
Geometry-Enabled Radiation from Structured Paraxial Electrons
M. S. Epov, I. E. Shenderovich, S. S. Baturin
We present a microscopic calculation of spontaneous photon emission by twisted (paraxial) electrons propagating through inhomogeneous, axisymmetric magnetic fields. We construct ex…
Analytical theory of the skewed wake effect
A. N. Chuprina, S. S. Baturin
Recently, the experimental discovery of a new type of wakefield effect, the "skewed wake effect", has been reported. We provide an explanation of the nature of the skewed wake effe…
