Some remarks on the extended Galilean transformation

Greenberger, Daniel M.·1979·American Journal of Physics

Abstract

The Galilean transformation carries one inertial frame into another with a different velocity. The extended Galilean transformation carries an inertial frame into a rigid frame with uniform spatial, but arbitrary translational acceleration x′=x+ξ (t). Besides being useful in discussing the equivalence principle, this transformation provides a physical interpretation for the theorem in nonrelativistic quantum mechanics, that we cannot coherently combine states of different mass. This restriction comes about because we cannot distinguish between coordinate and proper time in nonrelativistic physics.

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?

  • To ensure covariance of the Schrödinger equation, the wave functions ψ and ψ' in the two reference frames differ by a mass-dependent phase term, which could cause mass-dependent diffraction and interference effects.

    “However, to ensure covariance of the Schr¨ odinger equation the wave functions ψ and ψ ' in the two reference frames differ each other for a massdependent phase term [Eqs.(3) and (4)], which could eventually cause mass-dependent diffraction and interference effects [8,34].”

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.
