Robustness of Off-Axis Electron Vortices in Nonuniform Magnetic Fields
Hui-Dong Huang, Qi Meng, Zhi-Bin Wang +3
Rotational symmetry protects the topological charge of on-axis electron vortices but not of off-axis vortices. We identify an additional SU(1,1) dynamical invariant that guarantees…
The influence of the transverse electric field on accelerating vortex state in the axisymmetric electric field
Ziyang Ding, Ziqiang Huang, Qi Meng +3
The relativistic vortex states of massive charged particles propagating in non-uniform axisymmetric electric field are studied. Starting from the stationary-state equation after th…
Radiation of breathing vortex electron packets in magnetic field
G. V. Zmaga, G. K. Sizykh, D. V. Grosman +4
When a vortex electron with an orbital angular momentum (OAM) enters a magnetic field, its quantum state is described with a nonstationary Laguerre-Gaussian (NSLG) state rather tha…
Orbital angular momentum radiation and polarization of relativistic electrons in magnetic fields
Ziqiang Huang, Qi Meng, Xuan Liu +6
While spin polarization from synchrotron radiation is well established, the polarization of orbital angular momentum (OAM) in such radiative processes remains elusive. We study rad…
Relativistic quantum mechanics of charged vortex particles accelerated in a uniform electric field
Qi Meng, Ziqiang Huang, Xuan Liu +6
The relativistic quantum-mechanical description of a charged Laguerre-Gauss beam accelerated in a uniform electric field has been fulfilled. Stationary wave eigenfunctions are rigo…
Generalized Gouy Rotation of Electron Vortex beams in uniform magnetic fields
Qi Meng, Xuan Liu, Wei Ma +5
The intrinsic rotation of electron vortex beams, governed by their phase structure, has been experimentally observed in magnetic fields by breaking the beam's cylindrical symmetry.…
