The best reference for AB effect that I have come across until now, is Ryder's QFT. It starts by describing the effect, and calculating the phase change as usual. But, then he digs further and gives the topological explanation of the Aharanov-bohm effect as the non simply connectedness of the gauge group of electromagnetism (U(1)). It also described homotopy ...
