Topologically robust programmable processing arrays using light and matter skyrmions

Abstract Photonic computing offers a low-power, high-bandwidth paradigm for information processing; however, the analog nature of conventional architectures means that intrinsic noise and fabrication imperfections greatly impact performance, thereby severely limiting scalability....

Field-Programmable Topological Torons in Chiral Nematic Liquid Crystals

Abstract Torons are three-dimensional double-twist solitons in chiral nematic liquid crystals (LCs), bounded by closed defect loops, that behave as particle-like entities while retaining a fully reconfigurable optical response. Here, it is shown that individual torons can be crea...
