Fractional Skyrme lines in ferroelectric barium titanate
Chris Halcrow, Egor Babaev
We predict a topological defect in ferroelectric barium titanate which we call a skyrme line. These are line-like objects characterized by skyrmionic topological charge. As well as…

Ferroelectric domain wall clusters in barium titanate
Chris Halcrow, Egor Babaev
We study ferroelectric domain walls in barium titanate. We search for structurally nontrivial, so-called non-Ising domain walls, where the Polarisation is non-zero along the entire…
