2019年4月19日，华中科技大学刘鑫教授，应我院许东辉副教授邀请，为学院师生带来题为“Lattice symmetry assisted second-order topological superconductors and Majorana patterns”的学术报告。在报告中刘鑫教授首先回顾了凝聚态物理中的马约拉纳费米子以及它在拓扑超导中实现的实验进展，之后介绍了当前拓扑态的热门研究方向-高阶拓扑相的研究现状，并介绍了他的研究组在一类二维高阶拓扑超导体中实现马约拉纳转角态(Majorana corner states)的理论进展。报告结束后，刘鑫教授与在场师生们关于马约拉纳费米子、高阶拓扑超导体和绝缘体进行了更加深入的讨论。
