Aharonov-Bohm and Berry Phases for a Quantum Cloud of Charge
Aharonov-Bohm and Berry Phases for a Quantum Cloud of Charge
We investigate the phase accumulated by a charged particle in an extended quantum state as it encircles one or more magnetic fluxons, each carrying half a flux unit. A simple, essentially topological analysis reveals an interplay between the Aharonov-Bohm phase and Berry's phase.
