the massless Dirac fermions, in a non-relativistic set-up. In such Dirac materials, two doubly degenerate bands contact at discrete momentum points called Dirac points, and disperse linearly along ...

However, the levels in ZrSiS followed an unusual pattern, aligning with a theoretical “B^(2/3) power law” that had been predicted as a signature of semi-Dirac fermions. The experiment thus ...

named after mathematician Paul Dirac whose eponymous equation describes these fermions. Now, a new study claims to have spotted these particles in a semimetal material, which conducts electricity ...

Dirac fermions have been studied intensively in condensed matter physics in recent years. Many theoretical predictions critically depend on the number of valleys where the Dirac fermions are realized.

Quantum Hall effect in a bulk antiferromagnet EuMnBi2 with magnetically confined two-dimensional Dirac fermions. Science Advances , 2016; 2 (1): e1501117 DOI: 10.1126/sciadv.1501117 Cite This Page : ...

The third group found evidence for type-II Dirac fermions in a similar material called platinum ditelluride. Dirac fermions are subatomic particles with half-integer spin that are not their own ...

These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles with contextual behaviors are of interest for quantum computing and superconductors.

When matter and antimatter annihilate or decay, they will heat a system up by a different amount depending on whether the particles obey Fermi-Dirac statistics (for fermions) or Bose-Einstein ...

Known as semi-Dirac fermions, particles with this bizarre behavior were first predicted 16 years ago. The discovery was made in a semi-metal material called ZrSiS, made up of zirconium ...

For example, electrons and protons are fermions whereas photons are bosons. Fermions can be further classified as Dirac or Majorana fermions. Dirac fermions are fermions that may or may not have ...

Such charge carriers are called 3D Dirac fermions. Being massless, 3D Dirac fermions travel at a constant, typically quite high speed through the 3DTDS, resulting in unusually high conductivity ...
