Weyl Semimetals Review, The Weyl semimetals could be used to build a range of electronic devices, from superlenses for scanning tunneling microscopes to transistors. The pole, at these Weyl nodes. We begin this review with an introduction and a discussion of Weyl fermions as emergent particles in condensed matter systems, and explain how high energy phenomena like the chiral anomaly can be Depending on the geometry of their Fermi surfaces, Weyl semimetals and their analogs in classical systems have been classified into two types. , Das Sarma, S. The Fe–Sn films on glass substrates exhibit large anomalous Hall and Nernst effects comparable to those of the single crystals of topological semimetals Fe3Sn2 and Fe3Sn. Magnetic Weyl semimetals are promising materials for spintronic applications due to their unique prop-erties in bulk and surface topological states and the rich interplay between band topology and Liu, H W, Richard, P, Zhao, L X, Chen, G-F, Ding, H (2016) Comparative Raman study of Weyl semimetals TaAs, NbAs, TaP and NbP. , In Weyl semimetals, the band crossing points or Weyl nodes serve as monopole or antimonopole for the Berry curvature flux in the momentum space. This leads to many Weyl metal is the first example of a conducting material with a nontrivial electronic structure topology, making it distinct from an ordinary metal. Weyl fermions possess exotic properties and can act like magnetic monopoles. However, so far, Weyl physics remain We review the basic concepts and compare these topological states of matter from the materials perspective with a special focus on Weyl semimetals. Topological Dirac In this concise review, recent developments of quantum transport in two typical topological semimetals, namely Dirac and Weyl semimetals, are described. Physical Review B, 93 (4) doi:10. We show that the coupling of circularly Abstract Weyl semimetals have attracted significant interest in condensed matter physics and materials science, due to their unique electronic and topological We begin this review with an introduction and a discussion of Weyl fermions as emergent particles in condensed matter systems, and explain how high energy phenomena like the chiral anomaly can be In recent years many three-dimensional crystals have been discovered whose low energy electronic properties are described by the Dirac or Weyl equations for relativistic fermions. The TaAs family is the ideal materials class to The researchers provide their outlook on future works on the emerging topic of photonics based on Weyl semimetals. We aim to expound our perspectives on the key results and the We first outline the key theoretical principles and distinctive properties of Weyl semimetals, followed by an examination of recent advancements that enhance their functional versatility. So far, most works on Weyl semimetals focus on novel physics. This review envisions the practical application spectrum of magneto-electrocatalysis through materials and mechanistic insights, projecting new directions that could redefine future catalytic science. After discussing the MR for different samples of TaAs2 and other semimetals, we Weyl and Dirac semimetals are three dimensional phases of matter with gapless electronic excitations that are protected by topology and symmetry. H. 241112 We show that nonreciprocal surface plasmon polaritons in time-reversal symmetry-breaking systems, including magneto-optical materials and magnetic Weyl semimetals, can alter the symmetry of This is a tutorial review of the optical properties and applica-tions of Weyl semimetals. In this review, we undergo a concise journey from graphene based Dirac physics to Heusler compounds, Weyl semimetals and the Berry phase are three current research fields of great interest. This Review surveys the Weyl semimetals are topological materials whose electron quasiparticles obey the Weyl equation. Physical Review B, 99 (11) doi:10. Possible exploitation of topologically protected Semiconductors and semimetals represent distinct material classes, with semiconductors forming the foundation of modern electronics and semimetals In this review, we undergo a concise journey from graphene based Dirac physics to Weyl semimetals: the underlying Hamiltonians, their basic features and their unique response to external electric and Weyl-semimetals are a particular class of materials of recent focus due to the topological protection of the Weyl-nodes, resulting in a number of fundamentally interesting phenomena. 99. We review the basic concepts and optical responses of Weyl semimetals, and survey their applications in optics and Abstract Weyl semimetals have attracted significant interest in condensed matter physics and materials science, due to their unique electronic and topological properties. In type-I Weyl semimetals (WSMs), the conelike In this article, we review the exciting and rapidly developing subject of Weyl semimetals, focusing on response and transport phenomena.
