Derivation of the geometrical phase
Arno Böhm, Luis J. Boya, Brian K. Kendrick
Abstract
The geometric (Berry) phase is shown to have its origin in the nontrivial geometry of the fiber bundle: Hilbert space\ensuremath{\rightarrow}space of states. The nontrivial geometry comes simply from the scalar product in Hilbert space. A comprehensive treatment of the geometrical phase is presented, bringing together the various ideas in the literature.
