Electron localization by a magnetic vortex
We study the problem of an electron in two dimensions in the presence of a magnetic vortex with a step-like profile. Dependending on the values of the effective mass and gyromagnetic factor of the electron, it may be trapped by the vortex. The bound state spectrum is obtained numerically, and some limiting cases are treated analytically.

متن کاملElastic Scattering of Electron Vortex Beams in Magnetic Matter.
Elastic scattering of electron vortex beams on magnetic materials leads to a weak magnetic contrast due to Zeeman interaction of orbital angular momentum of the beam with magnetic fields in the sample. The magnetic signal manifests itself as a redistribution of intensity in diffraction patterns due to a change of sign of the orbital angular momentum of the electron vortex beam. While in the ato...
متن کاملMagnetic Vortex
Direct observations of vortex structure only appear recently; in this essay we will examine these first observations. And then introduce experiments and theory about the dynamics of vortex core; meanwhile we will propose the principle of chirality conservation in vortex; and with this idea we present another explanation in Bussmann’s experimental results. Finally, reveal the high possible appli...
متن کاملLocalization of quasiparticles in a disordered vortex
We study the diffusive motion of low-energy normal quasiparticles along the core of a single vortex in a dirty, type-II, s-wave superconductor. The physics of this system is argued to be described by a one-dimensional supersymmetric nonlinear σ model, which differs from the σ models known for disordered metallic wires. For an isolated vortex and quasiparticle energies less than the Thouless ene...
