Abstract

Three-dimensional (3D) topological semimetals represent a new class of topological matters. The study of this family of materials has been at the frontiers of condensed matter physics, and many breakthroughs have been made. Several topological semimetal phases, including Dirac semimetals (DSMs), Weyl semimetals (WSMs), nodal-line semimetals (NLSMs), and triple-point semimetals, have been theoretically predicted and experimentally demonstrated. The low-energy excitation around the Dirac/Weyl nodal points, nodal line, or triply degenerated nodal point can be viewed as emergent relativistic fermions. Experimental studies have shown that relativistic fermions can result in a rich variety of exotic transport properties, e.g., extremely large magnetoresistance, the chiral anomaly, and the intrinsic anomalous Hall effect. In this review, we first briefly introduce band structural characteristics of each topological semimetal phase, then review the current studies on quantum oscillations and exotic transport properties of various topological semimetals, and finally provide a perspective of this area.

拓扑半金属的输运

三维拓扑半金属是一类新的拓扑物质。对这类材料的研究一直处于凝聚态物理的前沿，并取得了许多突破。几种拓扑半金属相，包括狄拉克半金属(DSMs)， Weyl半金属(WSMs)，节线半金属(nlsm)和三点半金属，已经从理论上预测和实验证明。在Dirac/Weyl节点、节点线或三重简并节点周围的低能激发可以看作是涌现的相对论性费米子。实验研究表明，相对论性费米子可以产生丰富多样的奇异输运性质，如极大的磁阻、手性异常和本征异常霍尔效应。本文首先简要介绍了各拓扑半金属相的能带结构特征，然后综述了各种拓扑半金属的量子振荡和外来输运性质的研究现状，最后展望了该领域的发展前景。
