Rotational Frequency Shift of a Light Beam

Abstract

We explain the rotational frequency shift of a light beam in classical terms and measure it using a mm-wave source. The shift is equal to the total angular momentum per photon multiplied by the angular velocity between the source and observer. This is analogous to the translational Doppler shift, which is equal to the momentum per photon multiplied by the translational velocity. We show that the shifts due to the spin and orbital angular momentum components of the light beam act in an additive way.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • In the momentum representation, the spin-orbit interaction of light acquires the same form as the spin-orbit interaction of electrons stemming from the Dirac equation.

    “In such representation, the spin-orbit interaction of light, Eq. (3.16), acquires the same form as the spin-orbit interaction of electrons stemming from the Dirac equation [29,32,54,81 -83].”
  • A curvilinear coordinate system based on unit vectors (u1, u2, t) is the only orthogonal coordinate system in the vicinity of the ray trajectory.

    “It is worth noticing that a curvilinear coordinate systems based on unit vectors 1 2 ( , , ) u u t is the only orthogonal coordinate system in the vicinity of the ray trajectory [81,87,157].”

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.
