WebAharonov-Bohm Effect : In General > s.a. Aharonov-Casher Effect; geometric phase; locality in quantum mechanics; topology in physics. * Idea: The phase difference Δφ = (e/\(\hbar\)) Φ between the wave functions of two electrons going different ways around a line of magnetic dipoles with magnetic flux Φ; It was actually proposed by Ehrenberg and … The Aharonov–Bohm effect, sometimes called the Ehrenberg–Siday–Aharonov–Bohm effect, is a quantum mechanical phenomenon in which an electrically charged particle is affected by an electromagnetic potential (φ, A), despite being confined to a region in which both the magnetic field B and … See more In the 18th and 19th centuries, physics was dominated by Newtonian dynamics, with its emphasis on forces. Electromagnetic phenomena were elucidated by a series of experiments involving the … See more The magnetic Aharonov–Bohm effect can be seen as a result of the requirement that quantum physics must be invariant with respect to the gauge choice for the electromagnetic potential, of which the magnetic vector potential $${\displaystyle \mathbf {A} }$$ forms … See more In 1975 Tai-Tsun Wu and Chen-Ning Yang formulated the non-Abelian Aharonov–Bohm effect, and in 2024 this was experimentally reported in a system with light waves … See more The Aharonov–Bohm effect can be understood from the fact that one can only measure absolute values of the wave function. While this … See more Just as the phase of the wave function depends upon the magnetic vector potential, it also depends upon the scalar electric potential. … See more The Aharonov–Bohm phase shift due to the gravitational potential should also be possible to observe in theory, and in early 2024 an experiment was carried out to observe it based on an experimental design from 2012.
