摘要：

自旋-轨道耦合场、克雷默系统内的原子磁场或离散对称性可以在布里渊区中创建拓扑环面并提供受保护的边缘或表面态，其可以包含相对论费米子，即狄拉克费米子和外尔费米子。拓扑保护的螺旋边缘或表面态和体电子能带定义了物质的不同量子或拓扑相，为一些独特的器件应用提供了良好的前景。量子材料的器件应用主要依赖于理解其拓扑性质、在不同外界刺激下的相互转换过程以及实现相变的物理系统。人们一直在努力寻找具有奇异拓扑相的新拓扑材料。然而，由于用于控制拓扑相变的物理结构的发展缓慢，拓扑性质在器件中的应用仍然受到限制。这种控制系统通常需要极端的调谐条件或复杂的多层拓扑结构的制造。这篇综述文章重点介绍了拓扑相的细节，它们的转换过程，以及它们潜在的物理系统和潜在的应用领域。进一步讨论了拓扑相和材料性质的关键因素的一般概述，为以下部分提供必要的背景。

英文摘要：

The spin-orbit coupling field, an atomic magnetic field inside a Kramer's system, or discrete symmetries can create a topological torus in the Brillouin Zone and provide protected edge or surface states, which can contain relativistic fermions, namely, Dirac and Weyl Fermions. The topology-protected helical edge or surface states and the bulk electronic energy band define different quantum or topological phases of matters, offering an excellent prospect for some unique device applications. Device applications of the quantum materials rely primarily on understanding the topological properties, their mutual conversion processes under different external stimuli, and the physical system for achieving the phase conversion. There have been tremendous efforts in finding new topological materials with exotic topological phases. However, the application of the topological properties in devices is still limited due to the slow progress in developing the physical structures for controlling the topological phase conversions. Such control systems often require extreme tuning conditions or the fabrication of complex multi-layered topological structures. This review article highlights the details of the topological phases, their conversion processes, along with their potential physical systems, and the prospective application fields. A general overview of the critical factors for topological phases and the materials properties are further discussed to provide the necessary background for the following sections.
