Moiré polar vortex, flat bands, and Lieb lattice in twisted bilayer BaTiO3

Through first-principles calculations based on density functional theory, we investigate the crystal and electronic structures of twisted bilayer BaTiO3. Our findings reveal that large stacking fault energy leads to a chiral in-plane vortex pattern that was recently observed in experiments. We also...
