Author(s): Zhi-Yang Wang, Fei Yang, and Long-Qing Chen Polar skyrmions in ferroelectric superlattices are nanoscale topological polarization textures typically regarded as weakly coupled objects confined to individual layers, with a role secondary to that of the underlying symmetry-breaking order parameter. Here, using large-scale phase-field simulation… [Phys. Rev. Lett. 137, 136602] Published Tue Sep 22, 2026
