Molecular dynamics in a first-principle-based effective Hamiltonian scheme show that optical rotation of polarized light as measured by gyrotropic coefficient is maximized at room temperature for some applied DC electric field in a ferroelectric nanocomposite consisting of BaTiO3 nanowires in an SrTiO3 medium that exhibits electrical vortices. Together with a phase diagram obtained from Monte Carlo simulation, this characterizes optical applications of electrical vortices.

The recently proposed coupling between the angular momentum density and magnetic moments is shown
to provide a straightforward alternative explanation for galvanomagnetic eects, i.e., for both anisotropic
magnetoresistance (AMR) and planar Hall eect (PHE). Such coupling naturally reproduces the general
formula associated with AMR and PHE and allows for the occurrence of so-called `negative AMR'. This
coupling also provides a unifying link between AMR, PHE and the anomalous Hall eect (AHE) since this
same coupling was previously found to give rise to AHE (Bellaiche et al 2013 Phys. Rev. B 88 161102).
