Theory of Polar Skyrmions in Layered Structure of Ferroelectric Perovskites

Snehasish Sen, Sudhansu S. Mandal

Discovery of polar skyrmions on the (PbTiO${}_3$)${}_n$/(SrTiO${}_3$)${}_n$ superlattice in the absence of any known interaction, which can orient electric polarizations at a point with re…
