  The non-trivial geometry encoded in the Quantum Mechanical wavefunctions has
important consequences for its single-particle as well as many-body dynamics.
Yet, our understanding of how the geometry of the single-particle eigenstates
are manifest in the characteristics of a many-particle system is still
incomplete. Here, we demonstrate how the single-particle Berry curvature
modifies the fluxoid quantization of a two dimensional
Bardeen-Cooper-Schrieffer (BCS) superconductor, and discuss the experimental
scenarios where this anomalous quantization is expected to be realized.
