TL;DR
This paper investigates whether the speed of light in vacuum varies with frequency when considering quantum effects, specifically the polarization of the Dirac sea, proposing a potential experimental test.
Contribution
It introduces a quantum perspective on vacuum dispersion by analyzing the Dirac sea's polarization and suggests a method to experimentally detect frequency dependence of light speed.
Findings
Theoretically estimates vacuum's index of refraction dependence on wavelength.
Proposes an experimental approach to test vacuum dispersion.
Challenges the classical notion of non-dispersive vacuum.
Abstract
The question we ask is: does the speed of light {\it{in vacuo}} depend on its frequency? While the answer is NO in the frame of classical physics, we point out that the opposite could be true if one takes into account the polarization of Dirac sea. We estimate the dependence of the index of refraction of vacuum + Dirac sea versus the wavelength of an incoming beam, and suggest a way to test this effect.
