Abstract: polar skyrmions in (PbTiO3)n/(SrTiO3)n superlattices suggests a perfect system for exploring interesting physical responses, including emergent toroidal order and local negative capacitance [1, 2]. Here, we explore the topologically non-trivial dipole textures of polar skyrmions,… read more here.

Abstract: Topological objects with skyrmionic textures in ferroelectrics, i.e., polar skyrmions, are promising technological paradigms in next-generation electronic devices. While breakthrough discoveries of stable polar skyrmions approximately ten nanometers in size have been very recently witnessed… read more here.
