Robust control over polar skyrmion bubble density with a combined optical and electrical approach
Lingyuan Gao, Laurent Bellaiche
Polar skyrmion bubbles are nanoscale ferroelectric domain configurations with swirling polarization textures, and often emerge in ferroelectric oxide systems. Owing to their inhomo…

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)…

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…
