Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called ...

Equation (1), as written, actually makes an implicit omission, which leads to a loss of an important piece of physics of Weyl semimetals. In general, the coefficient of the unit matrix σ0 is a ...

Weyl particles are not particles which can move on their own (like electrons or protons), they only exist as 'quasiparticles' within a solid material. Now, for the first time, such Weyl particles have ...

The quantum electronic link in momentum (velocity) space observed in the topological Weyl magnet Co 2 MnGa. (Courtesy: Ilya Belopolski and M Zahid Hasan, Princeton University) For the first time, a ...

Researchers have put forward a completely new heat transport mechanism – known as chiral zero sound – in Weyl semimetals. The new mechanism could explain recent observations of higher-than-predicted ...

The Hall effect is a mainstream direction in the study of condensed matter physics. Recently, the second-order Hall effect that does not require a magnetic field has recently been discovered in ...
