AB effect and Aharonov–Susskind charge non-superselection
AB effect and Aharonov–Susskind charge non-superselection
We consider a particle in a coherent superposition of states with different electric charges moving in the vicinity of a magnetic flux. Formally, it should acquire a (gauge-dependent) Aharonov–Bohm (AB) relative phase between the charge states, even for an incomplete loop. If measurable, such a geometric, rather than topological, AB …
