Topological transition from a hopfion to a toron via flexoelectric self-polarization in chiral liquid crystals

Physical Review Research
The presence of topological defects in apolar chiral liquid crystals causes orientational distortions, leading to nonuniform strain. This nonuniform strain generates an electric polarization response due to the flexoelectric effect, which induces an ...
