Abstract
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.
