Many papers have been published on the topic and the generally accepted view is that the Aharonov-Bohm effect is a purely quantum mechanical effect. Sep 3, 2019 The Aharonov-Bohm effect – where electron-interference fringe positions are shifted based on the presence of a non-local magnetic field – has It consists in multiplying the free evolution by a phase given by the integral in time of the potential. The validity of this ansatz predicts interference fringes between Aug 19, 2019 By changing the de Broglie wavelength of the electron wave function, the vector potential in the Aharonov-Bohm and Ehrenberg-Siday effect acts Oct 19, 2020 The Aharonov-Bohm effect is a configuration of the electromagnetic field which has vanishing electric/magnetic field strength (vanishing Abstract.

Solution . T HE A HARONOV-B OHM EFFECT it is exactly these questions that make the Aharonov-Bohm effect. 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 electric field E are zero.

In books it's infinite solenoid most of the time, which makes some regions of space not simply connected. What intrigues me is the fact that in real experiment we can't use infinite solenoid.

Now Michael Hohensee of the University of California, Berkeley, and his colleagues, have an idea for the gravitational equivalent of this experiment. Aharonov-Bohm effect: lt;p|>||||| The |Aharonov–Bohm effect|, sometimes called the |Ehrenberg–Siday–Aharonov–Bohm| effe World Heritage Encyclopedia, the In 1959, Yakir Aharonov and David Bohm stated that a potential was itself a fundamental physical entity, and would affect a charged particle even in a region in which there was no magnetic field, and therefore no force acting on the charged particle. They proposed the following experiment to verify the existence of the effect.
