Topological polarization states, such as vortices, Hopfions, and skyrmions, represent a groundbreaking area in ferroelectric physics, driven by nanoscale confinement and long-range electrostatic forces. While these states have been studied theoretically, experimental observations in freestanding ferroelectric nanostructures remain unexplored. Our research establishes a platform combining rigorous theoretical insights from topology and topological hydrodynamics with advanced experimental methods. These theoretical models, based on Arnold’s topology, predict and classify polarization states, guiding experimental design. To bridge theory and experiment, we developed a platform integrating theoretical methods, phase-field and atomistic simulations, and experimental data of high-resolution techniques, including piezoresponse force microscopy, Bragg coherent X-ray diffraction, and scanning transmission electron microscopy. While validation is ongoing, this platform enables the reconstruction and manipulation of topological states, including chirality switching, with promising applications in chiral optoelectronics, quantum devices, and neuromorphic systems
