Asymmetry of the Aharonov-Bohm diffraction pattern and Ehrenfest’s theorem
Donald H. Kobe, Valdir C. Aguilera-Navarro, Regina Maria Ricotta
The electron-diffraction pattern for two slits with magnetic flux confined to an inaccessible region between them is calculated. The Aharonov-Bohm effect gives a diffraction pattern that is asymmetric but has a symmetric envelope. In general, both the expected displacement and the kinetic momentum of the electron are nonzero as a consequence of the asymmetry. Nevertheless, Ehrenfest's theorems and the conservation of momentum are satisfied.
