Poincaré sphere engineering of dynamical ferroelectric topological solitons
Lingyuan Gao, Yijie Shen, Sergei Prokhorenko +2
Geometric representation lays the basis for understanding and flexible tuning of topological transitions in many physical systems. An example is given by the Poincaré sphere (PS) t…

Large photo-induced tuning of ferroelectricity in sliding ferroelectrics
Lingyuan Gao, Laurent Bellaiche
Stacking nonpolar, monolayer materials has emerged as an effective strategy to harvest ferroelectricity in two-dimensional (2D) van de Waals (vdW) materials. At a particular stacki…
