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 ...

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 : ...

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 ...

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 ...

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 ...

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 ...

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 ...

Semi-Dirac fermions were first theorized in 2008 and 2009 by several teams of researchers, including scientists from the Université Paris Sud in France and the University of California ...
