  • Title: Temperature reconfigurable skyrmionic solitons in cholesteric liquid crystals.
    Author: Shen Y, Qaiser M, Dierking I.
    Journal: Soft Matter; 2023 Dec 06; 19(47):9325-9331. PubMed ID: 38013505.
    Abstract:
    In this work, a reversible transformation between torons and cholesteric fingers is realized by continuously changing the pitch through temperature variation of the chiral nematic liquid crystal twist inversion system. By decreasing the pitch, the torons act as seeds from which cholesteric fingers gradually grow. By increasing the pitch, the cholesteric fingers gradually shorten and transform back to the initial state. We find that although the morphology of the torons is severely deformed and cannot be distinguished during the heating-cooling loops, the torons are very well topologically protected and can hardly be destroyed.
