| contents | 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 configurations with integer charge, the charge density can split into well-localized fractional parts. We show that under certain conditions the fractional skyrme lines are stable. We discuss a mechanism to create fractional topological charge objects and investigate their stability. |
