Liquid crystals enable on‑demand skyrmion formation at room temperature

Phys · · 722 words · By Krystal Kasal

Researchers have developed a method to create and control skyrmion structures in liquid crystals using light, heat, and electric fields at room temperature. This advancement may lead to more energy-efficient data storage and the development of reconfigurable topological photonics.
