Title: Tuning Polar Textures with Temperature Gradients
Abstract: Materials containing local dipole moments, such as ferroelectrics, are emerging as a new arena in which to explore topological textures. In analogy to magnetic materials, ferroelectrics can host domain walls, vortices, skyrmions and a plethora of other textures. These exotic phases can be created via epitaxial or superlattice engineering, and their properties tuned with external perturbations such as strain or electric fields.

A gradient in the temperature of a ferroelectric system is also a very powerful tool to engineer bespoke properties and textures in ferroelectrics. Using second-principles molecular dynamics, we show how a modulation in the temperature can lead to direct control of the orientation of electric dipoles. We then reveal how more complicated textures be created through appropriate application of temperature gradients.
