On the correlation of light polarization in uncorrelated disordered magnetic media

TL;DR

This paper theoretically investigates how light polarization correlations develop in uncorrelated disordered magnetic media, revealing magneto-optical effects on polarization in a Gaussian white noise disorder model.

Contribution

It provides a first-order analytical expression for the spatial field correlation matrix, including nonzero off-diagonal elements due to magneto-optical interactions.

Findings

Magneto-optical interaction induces polarization correlations.

Correlation matrix has nonzero off-diagonal elements.

First-order gyration effects are analytically derived.

Abstract

Light scattering in a magnetic medium with uncorrelated inclusions is theoretically studied in the approximation of ladder diagram. Correlation between polarizations of electromagnetic waves that are produced by infinitely-distant dipole source is considered. Here white noise disorder model with Gaussian distribution is taken into account. In such a medium the magneto-optical interaction leads to correlation between perpendicular light polarizations. Spatial field correlation matrix with nonzero nondiagonal elements is obtained in the first order on gyration.
