Novel static and dynamical properties of electric topological defects

This is the authors' abstract. We don't add key points for this paper.

This article highlights some recent works related to unusual static and dynamical properties of electric topological defects. A particular emphasis is put on Moiré patterns in twisted oxides, the application of twisted lights in ferroelectric thin films and the prediction of specific lattice vibrations responsible for the condensation of some electric topological defects. Some perspectives are also provided at the end of this article.
