Weyl semimetals
Weyl semimetals are a class of materials that exhibit unique electronic properties due to the presence of Weyl fermions, which are massless particles that behave like chiral quasiparticles. These materials have a special band structure where conduction and valence bands touch at discrete points called Weyl nodes.
The unique topology of Weyl semimetals leads to fascinating phenomena, such as the chiral anomaly and surface states known as Fermi arcs. These properties make Weyl semimetals promising candidates for applications in electronics and spintronics, potentially enabling faster and more efficient devices.
