Abstract
Recently Chiao and his collaborators proposed a novel scalar electric Aharonov-Bohm (AB) effect [Phys. Rev. A 107, 042209 (2023)]. They claimed that a quantum system inside a Faraday cage with a time varying but spatially uniform scalar potential acquires an AB phase, resulting in observable energy level shifts. This comment argues that their analysis is flawed: a spatially uniform scalar potential inside the cage, despite external variations, can be gauged away without altering gauge-invariant observables, such as energy differences, thus invalidating their claim. A possible explanation of this seemingly puzzling result is also given.
