It is generally admitted that in quantum mechanics, the electromagnetic potentials have physical interpretations otherwise absent in classical physics as illustrated by the Aharonov-Bohm eﬀect. In 1984, Berry interpreted this eﬀect as a geometrical phase factor. The same year, Wilczek and Zee generalized the concept of Berry phases to degenerate levels and showed that a non-Abelian gauge ﬁeld arises in these systems. In sharp contrast with the Abelian case, spatially uniform non-Abelian gauge…
