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 ...

Band structure: Quasiparticles called semi-Dirac fermions were first theorized 16 years ago but were only recently spotted inside a crystal of semi-metal material called ZrSiS. At its crossing points, ...

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 ...

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.

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 ...

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 ...

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 ...

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.

This created a plasma of fast-moving Dirac fermions that exhibited a surprisingly high mobility despite frequent scattering. Both high mobility and neutrality of this Dirac plasma are crucial ...
