Abstract The basic aspects of the Aharonov–Bohm effect can be summarized by the remark that wavefunctions become sections of a line bundle with a flat connection (that is, a ”flat potential”). Passing at the level of quantum field theory in curved spacetimes, we study the Dirac field interacting with a classical (background) flat potential and show that it can be interpreted as a topological sector of the observable net of free Dirac field. On the converse, starting from a topological sector we… Expand
