Topological phonons in solids

这个项目的目的是通过对称性分析建立一个完整的时间反转不变系统中可能的拓扑声子列表，以确定理想的拓扑声子材料，并研究拓扑声子的相关性质和可能的应用。该项目的重要成果将是产生新的知识，这将有助于结束对新拓扑声子的搜索，并基于拓扑声子的完整分类列表预测新的拓扑声子材料。该项目的成果将揭开奇异的拓扑声子的物理机制，并为基于其前所未有的性质的拓扑声子材料的应用奠定坚实的基础。

This project aims to create a complete list of possible topological phonons in time-reversal-invariant systems via symmetry analysis, to determine ideal topological phononic materials, and to study topological phonon-related properties and possible applications. The significant outcomes of this project will be the generation of new knowledge that will help conclude the search for novel topological phonons and the prediction of novel topological phononic materials based on the complete classification list of topological phonons. The outcomes of this project should unlock the physics of the exotic topological phonons and lay a solid foundation for applying topological phononic materials based on their unprecedented properties.
