Help me check a fact about Berry phase

  1. May 22, 2015 #1
    I have vague memories of having read somewhere that if you have a parameter manifold that

    a) Have a non-trivial Berry phase (meaning the line integral of the berry connection is non zero for some curve)

    and

    b) the Berry curvature is non-singular anywhere in that manifold

    then you can always extend naturally that manifold to bigger one (so the original manifold becomes a submanifold of the new one) where the Berry curvature have singularities and that singularities act as the "source" of the Holonomy.

    It is that a fact or I'm misremembering something?
