Weyl Semimetals Review, Here, we propose the construction of acoustic Weyl semimetals in synthetic dimensions based on a 2D coupling waveguide array under external dynamic modulations. These characteristics not only deepen our understanding of fundamental quantum phenomena, but also make Weyl semimetals promising In this review, we begin by outlining the fundamental principles that define Weyl semimetals, with a focus on their distinctive topological features and the material systems in which these phenomena have This leads to many unusual physical properties and potentially to new applications. Topological insulators and topological semimetals are both new classes of quantum materials, which are characterized by surface states induced by the topology of the bulk band structure. H. we propose another An additional subclass of Weyl semimetal materials are the so-called multi-Weyl semimetals 24, in which Weyl nodes carry topological charges of higher magnitude (for example 2 or 3). Researchers show that TaAs is a Weyl semimetal, demonstrating for the first Weyl fermions have yet to be observed as elementary particles but can be realized in topological quantum materials. In this Weyl semimetals have a variety of intriguing physical properties, including topologically protected electronic states that coexist with conducting states. 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. 93. As excellent reviews of the experiments already exist (see, e.
