清华大学“世纪物理情” Classification and construction of  crystalline topological superconductors  and insulators in interacting fermion  systems 2024年6月19日 16:00 蔻享学术 扫码查看精彩直播 // 嘉宾简介 顾正澄 Prof Gu is an internationally recognized leading expert on topological phases of  quantum matter. In recent years, he and his collaborator had established a new  paradigm for topological phases based on the concept of long-range entanglement.  They further used classify topological phases of quantum matter in strongly correlated  electron systems and developed new mathematical framework such as super tensor  category theory and group super-cohomology theory. In particular, he and his  collaborator proposed a new class of topological phases protected by global symmetry - the so-called symmetry protected topological phase (SPT), which made significant contribution to 2016 physical Nobel Prize. Prof Gu and his collaborator further pointed ………………………………
