Aharonov-Bohm problem for spin 1
M. L. Horner, Alfred S. Goldhaber
Abstract
The basic AB problem is to determine how an unshielded tube of magnetic flux $\ensuremath{\Phi}$ affects arbitrarily long-wavelength charged particles impinging on it. For spin 1 at almost all $\ensuremath{\Phi}$ the particles do not penetrate the tube, so the interaction essentially is periodic in $\ensuremath{\Phi}$ (AB effect). Below-threshold bound states move freely only along the tube axis, and consequent induced vacuum currents supplement rather than screen $\ensuremath{\Phi}$. For a pure magnetic interaction the tube must be broader than the particle Compton wavelength, i.e., only the nonrelativistic spin-$1$ AB problem exists.
