Among them, Dirac semimetals 4,5,6 have received special attention, because they host relativistic particles, the massless Dirac fermions, in a non-relativistic set-up.

Realizing semi-Dirac fermions. Previous efforts to create semi-Dirac fermions relied on stretching graphene (a sheet of carbon just one atom thick) until the material’s two so-called Dirac points ...

For other particles, such as semi-Dirac fermions, it means fluctuating mass depending on the direction of magnetic fields. Related Story. Scientists Still Don’t Quite Know How Mass Arises; ...

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.

Dirac fermions are subatomic particles with half-integer spin that are not their own antiparticles. Electrons in solids can also exhibit particle-like collective behaviour that can be described in ...

Fermions are just one of the basic categories of particles, and almost all of them are Dirac, meaning they have a complementary and distinctive antiparticle—think electron and positron.

Scientists have accidentally discovered a particle that has mass when traveling in one direction, but no mass while moving in a different direction. Known as semi-Dirac fermions, particles with ...

Scientists have discovered a new magnet capable of controlling Dirac fermions with zero mass. This achievement will lead to a new field of study, strong correlated quantum transport of Dirac ...

Kagome magnets harbor so-called Dirac fermions, which Zeljkovic explained are quasiparticles characterized by zero mass and a linear energy-momentum dispersion in electronic band structure ...

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 ...
