Observability of2πrotations around an Aharonov-Bohm solenoid
P. A. Horváthy
Abstract
A rotation by 2\ensuremath{\pi} around an Aharanov-Bohm solenoid is shown to change the wave function of a charged spinless particle by a phase factor \ensuremath{\chi}=exp(ie\ensuremath{\varphi}/\ensuremath{\Elzxh}). For fermions the effect manifests itself as a phase shift in addition to the well-known sign change. A gedanken experiment is proposed for observation.
