1. Spiral Spiral Public

   We identify a ferroelectric topological structure, termed "dipole spiral," which exhibits a giant intrinsic piezoelectric response (>320 pC/N). This helical structure, primarily stabilized by entro…

2. Spiral_DFT Spiral_DFT Public

   Here, using first-principles calculations on PbTiO3 under biaxial tensile strain, we unveil a novel form of polar order: a chiral, non-collinear ferroelectric double helix. We find that the Pb- and…
