The relation between the Berry and the Anandan–Aharonov connections for U(𝒩) bundles
Arno Böhm, A. Mostafazadeh
Abstract
The geometric phase has been defined as the holonomy of two bundles with different base spaces and different connections. In this article we establish the relation between the Berry–Simon and the Anandan–Aharonov definitions for a large class of cyclic Hamiltonians (with 𝒩-fold degeneracy) using the classifying theorem for principal fiber bundles.
