Multimodal Topological Textures Arising from Coupled Structural Orders in SrTiO ₃

. These domains exhibit complex Bloch- and Néel-like antiferrodistortive configurations, with the Néel type being energetically preferred. We also stabilize antiferrodistortive vortex and antivortex structures that colocalize with polarization vortices and a modulated local strain field, producing trimodal topological textures. Our results extend topological-ordering concepts to nonpolar structural modes and open the door to the cross-control of distinct textures.
