Knots and links, with their unique and robust topological structures, play a vital role across various disciplines, including physics, life sciences, and light–matter interactions. As a representative ...

Topological magnetoelectric effect (TME), for example, the topological response of magnetization to an electric field in the same direction, is a hallmark phenomenon of axion insulator from the ...

Researchers have identified a class of quantum materials, called topological semimetals, that can split water into hydrogen fuel using nothing but sunlight, sidestepping the expensive platinum-based ...
