Aharonov-Bohm Effect: Real or Myth?

In summary, Yakir Aharonov and David Bohm conducted a groundbreaking experiment in 1959 that measured the "hidden potential" of free space, predicted by Maxwell's equations almost 100 years prior. The experiment involved cooling a superconducting magnetic ring to 9 degrees above Absolute Zero and observing the changes in the electronic state of a test beam of electrons passing through the field-free region of the ring. This effect, known as the Aharonov-Bohm Effect, has been confirmed by other physicists and provides evidence for a deeper "scalar potential" underlying magnetic forces. Similar effects have also been observed with electrostatic fields. Overall, the Aharonov-Bohm effect is a real and significant phenomenon in the field of electrod

Yakir Aharonov and David Bohm, conducted a seminal "electrodynamics" laboratory experiment ("Significance of Electromagnetic Potentials in Quantum Theory," The Physical Review, Vol. 115, No. 3, pp. 485-491; August, 1959). Aharonov and Bohm, almost 100 years after Maxwell first predicted their existence, succeeded in actually measuring the "hidden potential" of free space, lurking in Maxwell's original scalar quaternion equations. To do so, they had to cool the experiment to a mere 9 degrees above Absolute Zero, thus creating a total shielding around a superconducting magnetic ring

Totally screened, by all measurements, from the magnetic influence of the ring itself, a test beam of electrons fired by Aharonov and Bohm at the superconducting "donut," nonetheless, changed their electronic state ("wave functions") as they passed through the observably "field-free" region of the hole -- indicating they were sensing "something," even though it could NOT be the ring's magnetic field. Confirmed now by decades of other physicists' experiments as a true phenomenon (and not merely improper shielding of the magnet), this "Aharonov-Bohm Effect" provides compelling proof of a deeper "spatial strain" -- a "scalar potential" -- underlying the existence of a so-called magnetic "force-field" itself. (Later experiments revealed a similar effect with shielded electrostatic fields ...)
Is this thing for real? Have you heard of it? :confused:

Yes, Mk; the Aharonov-Bohm effect is real. As untenable as it seems, charged particles passing through a magnetic vector potential, even though it is a field free region of space, change the phase of their wavefunction. This has been easily demonstrated with superconductors.

The Aharonov-Bohm Effect is a well-documented and widely accepted phenomenon in the field of physics. The experiment conducted by Aharonov and Bohm in 1959, and subsequent experiments by other physicists, have provided strong evidence for the existence of a hidden scalar potential in free space. This potential, predicted by Maxwell's equations, was finally measured and confirmed by the Aharonov-Bohm experiment.

The fact that this effect was observed even when the magnetic field was shielded, suggests that there is a deeper underlying force at work, challenging our traditional understanding of magnetic fields as purely vector quantities. This phenomenon has been confirmed by numerous experiments over the decades, further solidifying its validity.

The Aharonov-Bohm Effect is a significant discovery in the field of physics and has opened up new avenues for research and understanding of the fundamental forces at work in our universe. It is not a myth, but a well-established and accepted phenomenon.
 

1. What is the Aharonov-Bohm effect?

The Aharonov-Bohm effect is a quantum mechanical phenomenon in which a charged particle is influenced by an electromagnetic field, even though the particle never actually enters the region where the field is present.

2. Is the Aharonov-Bohm effect real or just a myth?

The Aharonov-Bohm effect is a well-established and experimentally verified phenomenon in quantum mechanics. Numerous experiments have been conducted to confirm its existence.

3. How does the Aharonov-Bohm effect challenge traditional notions of causality?

The Aharonov-Bohm effect challenges traditional notions of causality because it suggests that the electromagnetic field, which is thought to be responsible for the motion of charged particles, can affect particles even when they are not in its presence.

4. What are some real-world applications of the Aharonov-Bohm effect?

While the Aharonov-Bohm effect may seem like a purely theoretical concept, it has potential applications in quantum computing and communication, as well as in the development of more accurate sensors and detectors.

5. How does the Aharonov-Bohm effect fit into the larger framework of quantum mechanics?

The Aharonov-Bohm effect is just one of many phenomena that demonstrate the strange and counterintuitive nature of quantum mechanics. It highlights the importance of considering non-local effects and the interconnectedness of particles in quantum systems.
