摘要:

拓扑物态研究是凝聚态物理领域的热点之一。由于宏观特性,声子晶体等经典体系被视为模拟拓扑物理的优秀平台。科学上,这类研究可促成对经典、量子拓扑物态统一完备的理解,甚至领先于量子体系提出、发现一些有趣的拓扑物理效应和现象;应用上,这类基础研究可为研制性能卓越的新型声功能器件提供理论依据和知识储备。报告人将介绍本课题组近几年在拓扑声子晶体方面的研究进展,包括一阶及高阶拓扑绝缘体、拓扑半金属的声学实现,拓扑BIC态的普适构建方案,以及三维拓扑缺陷态传输特性及应用等。

Abstract: Topological states of matter research is one of the hot topics in the field of condensed matter physics. Due to their macroscopic properties, classical systems such as phononic crystals are considered excellent platforms for simulating topological physics. Scientifically, such research can lead to a comprehensive understanding of classical and quantum topological states of matter, and even advance the discovery of interesting topological physical effects and phenomena before their proposal in quantum systems. On the application side, this fundamental research can provide theoretical foundations and knowledge reserves for the development of high-performance novel acoustic devices. The speaker will introduce the research progress in the field of topological phononic crystals by our research group in recent years, including the acoustic realization of first-order and higher-order topological insulators, topological semimetals, universal construction schemes for topological bound states in the continuum, as well as the transport properties and applications of three-dimensional topological defect states.
