Manipulating Ferroelectric Topological Polar Structures with Twisted Light

We demonstrate dynamic control of ferroelectric order in quasi-2D CsBiNb2O7 using twisted ultraviolet light carrying orbital angular momentum. Our approach harnesses non-resonant multiphoton absorption and induced strain to modulate topological of ferroelectric polarization textures. In-situ X-ray coherent imaging and Raman spectroscopy reveal reversible, nanoscale polarization transitions, enabling efficient stabilization of topological solitons and paving the way for novel optoelectronic devices.
