A many-body Green's function framework extends topological band theory to orbital-symmetry-controlled chemical reactions, ...

Researchers led by Prof. Xiaoyong Hu at Peking University, China, are interested in topological photonics. They have proposed an interdisciplinary approach to study the topological systems through ...

On the left, the schematic illustration depicts the gluing rules of the Brillouin manifold, with a half-twist operation connecting the opposing faces. On the right, the BZ is divided into 64 blocks by ...

A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper ...

Contrary to conventional wisdom, so-called order parameters that distinguish symmetry-governed phases of matter can have topological structure. Symmetry constitutes a fundamental concept in physics.
