商品描述

This book provides a model description for the electromagnetic response of topological nodal semimetals and summarizes recent experimental findings in these systems. Specifically, it discusses various types of topological semimetals - Dirac, Weyl, nodal-line, triple-point, and multifold semimetals - and provides description for the characteristic features of the linear electrodynamic response for all these types of materials.
Topological semimetals possess peculiar bulk electronic band structure, which leads to unusual electrodynamic response. For example, the low-energy inter-band optical conductivity of nodal semimetals is supposed to demonstrate power-law frequency dependence and the intra- and inter-band contributions to the conductivity are often mixed. Further, the magneto-optical response is also unusual, because of the non-equidistant spacing between the Landau levels. Finally, in semimetals with chiral electronic bands, e.g. in Weyl semimetals, thesimultaneous application of parallel magnetic and electric fields leads to the chiral anomaly, i.e. to a misbalance between the electrons with diffident chiralities. This misbalance affects the electrodynamics properties of the material and can be detected optically. All these points are addressed here in detail.

The book is written for a wide audience of physicists, working in the field of topological condensed matter physics. It gives a pedagogical introduction enabling graduate students and non-experts to familiarize themselves with the subject.

商品描述(中文翻譯)

本書提供了拓撲節點半金屬的電磁響應模型描述，並總結了這些系統中的最新實驗發現。具體而言，它討論了各種類型的拓撲半金屬——Dirac、Weyl、節點線、三重點和多重半金屬——並對這些材料的線性電動力學響應特徵進行了描述。

拓撲半金屬擁有特殊的體電子能帶結構，這導致了不尋常的電動力學響應。例如，節點半金屬的低能量帶間光學導電率應該顯示出冪律頻率依賴性，且導電率的內帶和帶間貢獻通常是混合的。此外，磁光響應也很不尋常，因為Landau能級之間的間距不均勻。最後，在具有手性電子能帶的半金屬中，例如Weyl半金屬，平行施加磁場和電場會導致手性異常，即不同手性的電子之間的失衡。這種失衡影響材料的電動力學特性，並可以通過光學方式檢測到。所有這些要點在此都有詳細的討論。

本書是為廣泛的物理學家讀者撰寫的，特別是那些在拓撲凝聚態物理領域工作的研究者。它提供了一個教學性的介紹，使研究生和非專家能夠熟悉這一主題。

作者簡介

Artem Pronin graduated from the Moscow Physics and Engineering Institute in 1994. His PhD research was conducted at the A. M. Prokhorov Institute of General Physics of the Russian Academy of Sciences, Moscow, and was devoted to infrared and THz spectroscopy of superconductors. During his PhD studies, he spent a research term at the University of Augsburg, and in 1998, he received his PhD in solid-state physics from the Moscow Institute of Physics and Technology. Afterwards, he held postdoctoral positions at McMaster University, Canada, at Leiden University in the Netherlands, and at the University of Leeds, UK. During these terms, he studied various optical spectroscopic methods and investigated a variety of materials, which exhibited electronic correlations. In 2006, he joined the High Magnetic Field Laboratory in Dresden, Germany, where he carried out experimental optical investigations in high magnetic fields before moving to the University of Stuttgart in 2015. There, he has been leading a group at the 1st Physics Institute, which investigates optical properties of different topological materials, particularly of Weyl and Dirac semimetals. Overall, Artem Pronin has more than 70 publications on infrared, THz, and dielectric properties of superconductors, materials with strong electronic correlations, and topological materials.
