Significance of Electromagnetic Potentials in the Quantum Theory

Abstract

In this paper, we discuss some interesting properties of the electromagnetic potentials in the quantum domain. We shall show that, contrary to the conclusions of classical mechanics, there exist effects of potentials on charged particles, even in the region where all the fields (and therefore the forces on the particles) vanish. We shall then discuss possible experiments to test these conclusions; and, finally, we shall suggest further possible developments in the interpretation of the potentials.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The discovery of the AB effect confirmed the physical reality of gauge potentials and the nonlocality of gauge interactions.

    “The AB effect covers a group of phenomena associated with the path-dependent phase factors for particles traveling in a field-free region, but with irremovable gauge potential , the discovery of which confirmed the physical reality of gauge potentials and the nonlocality of gauge interactions56,57.”

    From Non-Abelian gauge field optics (2019) · cites this paper as [56]

    Section 5 says potentials can be physically effective for electrons in field-free regions, supporting that part of the claim. But it describes nonlocal interaction as one possible theoretical direction, alongside retaining a local theory; it does not say the effect confirmed nonlocal gauge interactions. Section 3 also says no direct experiment had yet confirmed the predicted effect. (LLM, conf=0.88)

  • The missing charge should not be identified with the concept of an emergent quasiparticle.

    “Wedemonstrate that the missing charge should not be identified with the concept of an emergent quasiparticle by showing that ∆ q ℏ ∮ A · d l does not correspond to the Aharonov-Bohm phase [2] acquired as the probe traverses a loop in space.”
  • The Aharonov-Bohm effect is a phenomenon in which charged particles feel electromagnetic potentials even in regions with no magnetic field.

    “Aharonov-Bohmov efekt [2] je fenomen u kojem nabijene ˇ cestice osje´ caju utjecaj elektromagnetskih potencijala ˇ cak i u podruˇ cjima gdje nema magnetskog polja.”
  • Bi2Se3 and related materials have been proposed as three-dimensional topological insulators with a single Dirac cone on the surface and verified by angle-resolved photoemission spectroscopy experiments.

    “3D topological insulators with the simplest possible surface states consisting of a single Dirac cone, on the other hand, have been proposed theoretically [10] in stoichiometric compounds Bi 2 Se 3 , Bi 2 Te 3 and Sb 2 Te 3 , and topological surface states have been observed independently by angle-resolved photoemission spectroscopy (ARPES) experiments in Bi 2 Se 3 [11].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
