Corroborated by numerical solutions of the linear massless Dirac-Weyl equation, we show that pseudospin can turn into orbital angular momentum completely, thus upholding the belief that pseudospin ...

The bulk electrons in topological semimetals are described by an ultra-relativistic dispersion relation, E(k) = ±ħv F σ · k, that resembles the Weyl equation for massless spin-1/2 ...

First predicted in 1929, Weyl fermions also have unique properties that could make them useful for creating high-speed electronic circuits and quantum computers. In 1928 Paul Dirac derived his ...

After physician Paul Dirac had arrived at his Dirac equation in 1928, which can be used to describe the behaviour of relativistic electrons, Hermann Weyl found a particular solution for this ...

Weyl fermions were first predicted in 1929 by the theoretical physicist Herman Weyl, who identified them as possible solutions of the Dirac equation. Electrons of the Weyl type behave very differently ...

The 3D Dirac point is a fourfold band crossing in 3D momentum space, which can be view as the degeneracy of two opposite Weyl points. However, the 3D Dirac points can be described by the Z2 ...

including Dirac and Weyl semimetals. Building on recent theoretical studies, researchers at the University of Science and Technology of China recently set out to experimentally observe a new class ...

At the heart of Dirac materials' unique properties is the Dirac cone, a linear dispersion of the electronic band structure near the Fermi level. This feature results in electrons moving through the ...

Dirac fermions are the most famous, comprising all matter. Physicists recently discovered Majorana fermions, which might form the basis of future quantum computers. Lastly, Weyl fermions exhibit ...

including Dirac and Weyl semimetals. "Our inspiration stemmed from a prior theoretical study that proposed a type of exceptional point (EP) termed Dirac EPs," Xing Rong, senior author of the paper ...
