Weyl semimetals is a class of topological materials characterized by the presence of Weyl nodes in their bulk electronic band structure. This research area within condensed matter physics investigates the unique electronic and transport properties arising from these topologically protected point degeneracies, where quasiparticle excitations behave as massless chiral Weyl fermions with linear dispersion near the nodes. Key characteristics include the topological charge associated with the Weyl nodes and the manifestation of phenomena such as the chiral anomaly, making them significant for exploring fundamental physics concepts, establishing connections to high-energy physics, and developing novel quantum electronic devices.
