Weyl Semimetals Review. This leads to many unusual physical properties and potential

This leads to many unusual physical properties and potentially to new applications. These Weyl semimetals are semimetals or metals whose quasiparticle excitation is the Weyl fermion, a particle that played a crucial role in quantum field theory but has not been observed as a Photoemission spectroscopy measurements have confirmed the TaAs class and WTe 2 class of Weyl semimetals as type-I and type-II, We review the basic concepts and compare these topological states of matter from the materials perspective with a special focus on Weyl semimetals. We first outline the key theoretical principles and distinctive properties of Weyl semimetals, followed by an examination of recent We review the basic concepts and optical responses of Weyl semimetals, and survey their applications in optics and thermal photonics. Equation (1), as written, actually makes an implicit omission, which leads to a loss of an important piece of physics of Weyl Since the time semimetals were theoretically proposed, the experimental observation of Weyl fermion was found in the chemical vapour transport (CVT) grown TaAs nonmagnetic In this concise review, recent developments of quantum transport in two typical topological semimetals, namely Dirac and Weyl Weyl fermions have yet to be observed as elementary particles but can be realized in topological quantum materials.
