Comment on “Role of potentials in the Aharonov-Bohm effect”

Yakir Aharonov, Eliahu Cohen, and Daniel Rohrlich Are the electromagnetic scalar and vector potentials dispensable? Vaidman [Phys. Rev. A 86, 040101(R) (2012)] has suggested that local interactions of gauge-invariant quantities, e.g., magnetic torques, suffice for the description of all quantum electromagnetic phenomena. We analyze six thought experiments that challenge this suggestion. All of them have explanations in terms of local interactions of gauge-dependent quantities, and,... Read more →
