Recently, the Dirac and Weyl semimetals have attracted extensive attention in condensed matter physics due to both the fundamental interest and the potential application of a new generation of electronic devices. Here we review the exotic electrical transport phenomena in Dirac andWeyl semimetals. Section 1 is a brief introduction to the topological semimetals（TSMs）. In Section 2 and Section 3, the intriguing transport phenomena in Dirac semimetals（DSMs） andWeyl semimetals（WSMs） are reviewed, respectively. The most widely studied Cd_3A_（s2） and the TaAs family are selected as representatives to show the typical properties of DSMs and WSMs, respectively. Beyond these systems, the advances in other TSM materials,such as ZrTe_5 and the MoTe_2 family, are also introduced. In Section 4, we provide perspectives on the study of TSMs especially on the magnetotransport investigations.

隧道维护可以避免隧道病害引发的安全事故,有效的维护依赖于全面和准确的隧道病害检测。传统的隧道病害检测依靠人工巡检,受隧道照明不足、检测时间短等因素的影响,检测效率低下且准确率低。针对这些隧道病害检测中的难题,根据轨交隧道结构均匀、轨道线路固定的特点设计了轨交隧道病害检测系统。系统将激光扫描技术与摄影测量技术相结合,使用激光扫描仪获取隧道三维点云,使用多线阵相机获取隧道影像,借助激光跟踪仪并设计虚拟靶标场对相机和扫描仪进行标定使其坐标基准统一。系统采用分布式的软件架构研发数据采集软件进行传感器交互和数据存储,并采用外触发的方法使传感器采集频率与车速匹配,最后基于Cesium框架研发数据管理平台对隧道数据进行管理。将系统应用于某隧道进行数据精度验证,实验表明轨交隧道病害检测系统能够在实际隧道中检测宽度为0.2 mm的裂缝和错台量0.5 mm的错台,具备轨交隧道病害检测能力。最后,通过将实验采集到的数据应用于隧道裂缝检测、错台检测、变形检测等方面,并对检测出的病害进行定位,证明了轨交隧道病害检测系统的实用性,为轨交隧道病害检测提供了可靠的解决方案。

As a manifestation of the underlying physical nature, quailtum oscillations with the applied magnetic field (B) are one of the most important topics in condensed matter physics. The research history can be tracked to 1930 when Lev Shubnikov and W. J. de Haas observed Shubnikov-de Haas (SdH) oscillations in the magnetoresistance (MR) of bismuth crystals. Since then, researchers have observed quantum oscillations in diverse materials, including metals, metallic compounds, semimetals, semiconductors and even insula tors, as well as in artificial mesoscopic microstructures . Nowadays, quantum oscillation detec ted by magneto transport investigation has been a powerful tool to detect the physical properties in solid-state systems.

Weyl fermion is a massless Dirac fermion with definite chirality,which has been long pursued since *** it has not been observed as a fundamental particle in nature,Weyl fermion can be realized as low-energy excitation around Weyl point in Weyl semimetal,which possesses Weyl fermion cones in the bulk and nontrivial Fermi arc states on the surface. As a firstly discovered Weyl semimetal,Ta As crystal possesses 12 pairs of Weyl points in the momentum space,which are topologically protected against small perturbations. Here,we report for the first time the tip induced superconductivity on Ta As crystal by point contact spectroscopy. The zero bias conductance peak as well as a conductance plateau with double conductance peaks and sharp double dips are observed in the point contact spectra simultaneously,indicating unconventional superconductivity. Our further theoretical study suggests that the induced superconductivity may have nontrivial topology. The present work opens a new route in investigating the novel superconducting states based on Weyl materials.
