Weylfermioner

Weyl fermions are a type of massless fermion that appear in high-energy physics and condensed matter physics. They were first proposed by Hermann Weyl in 1929 as a solution to the Dirac equation, which describes the behavior of fermions with relativistic speeds. Unlike Dirac fermions, which have both left- and right-handed components, Weyl fermions are chiral, meaning they only have one handedness. This chirality is a consequence of the fact that Weyl fermions are massless.

In condensed matter physics, Weyl fermions have been observed in certain materials, such as topological insulators and Weyl semimetals. These materials exhibit unique electronic properties, including the presence of surface states that are protected by topology. The surface states in these materials can be described by Weyl fermions, which move in a manner that is analogous to the behavior of massless particles in high-energy physics.

The discovery of Weyl fermions in condensed matter systems has led to significant interest in the field, as they offer a new platform for studying topological phases of matter and for developing new technologies, such as topological quantum computing. The study of Weyl fermions continues to be an active area of research, with ongoing efforts to better understand their properties and to find new materials that host these exotic particles.
