TL;DR
This paper proposes a Lorentz invariant model of spacetime-induced polarization fluctuations in photons, which predicts frequency-dependent effects observable in cosmic microwave background polarization measurements.
Contribution
It introduces a novel Lorentz invariant model for spacetime fluctuations affecting photon polarization, tested against recent CMB polarization data.
Findings
Model predicts frequency-dependent polarization effects.
Confronted with latest CMB polarization measurements.
Provides constraints on spacetime fluctuation models.
Abstract
A model of Lorentz invariant random fluctuations in photon polarization is presented. The effects are frequency dependent and affect the polarization of photons as they propagate through space. We test for this effect by confronting the model with the latest measurements of polarization of Cosmic Microwave Background (CMB) photons.
