Download PDF Abstract: In the seminal works from Santos and Gozalo [Europhys. Lett. $\mathbf{45}$, ()] and Marletto and Vedral [Phys. Rev. Lett. $\mathbf{}$, ()], it is shown how the Aharonov-Bohm effect can be described as the result of an exchange of virtual photons between the solenoid and the quantum charged particle along its propagation through the interferometer.

Aharonov-Bohm Effect - Rutgers University The Electric Aharonov-Bohm Effect. Ricardo Weder. In their seminal paper Aharonov and Bohm () claimed that electromagnetic fields can act at a distance on charged particles even if they are identically zero in the region of space where the particles propagate. They proposed two experiments to verify their theoretical conclusions.

The The Aharonov-Bohm Aharonov-Bohm effects: effects Figure 1 – Schematic of the Aharonov-Bohm (AB) and Ehrenberg-Siday (ES) two-slit interference experiments, where the magnetic field B is zero in the region outside the solenoid, yet the partial waves 1 and 2 for the electron e – recombine with different maxima and minima locations, depending on the vector potential A.

Aharonov–Bohm effect - Wikipedia Download PDF Abstract: A thought experiment is proposed to demonstrate the existence of a gravitational, vector Aharonov-Bohm effect. A connection is made between the gravitational, vector Aharonov-Bohm effect and the principle of local gauge invariance for nonrelativistic quantum matter interacting with weak gravitational fields.

Aharonov Bohm Effect Through its vector potential, Aθ = Φ/2πr (in cylindrical coordinates), the flux exerts an Aharonov–Bohm effect on the electrons. We can eliminate the vector potential with a gauge transformation at the cost of the boundary condition twisted to ψ (θ) → exp [i (Φ/ϕ 0)θ], on the wave function ψ, where ϕ 0 = eh/e is the flux quantum.

Notes 20: The Aharonov-Bohm effect - University of Delaware In Bohm and Aharonov presented a paper In which they pointed out the significance of electromagnetic potentials in quantum theory and actually suggested. Interference experiments to detect how potentials would affect the passage of electrons through field free regions.

Observation of a gravitational Aharonov-Bohm effect: Science Download PDF Abstract: The Aharonov-Bohm (AB) effect is a pure quantum effect that implies a measurable phase shift in the wave function for a charged particle that encircles a magnetic flux located in a region \textit{inaccessible} to the particle. Classically, such a non-local effect appears to be impossible since the Lorentz force depends on.
