Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

Indeed, when, in 1928, Paul Dirac discovered 1 the theoretical framework ... it must be its own antiparticle. Thus the photino is a Majorana fermion. So, for similar reasons, are various other ...

Dirac fermions – in both typical and quasiparticle form – have properties that come in opposing particle and antiparticle forms. This semi-Dirac fermion detailed in the new study is a strange ...

The British physicist Paul Dirac started the ball rolling in the late 1920s with his equation describing how relativistic electrons – and with it most other matter particles – behave.

Dirac cones, named after the renowned physicist Paul Dirac, are unique features found in the electronic band structures of certain materials, such as graphene and topological insulators. These cones ...

Dirac fermions – in both typical and quasiparticle form – have properties that come in opposing particle and antiparticle forms. This semi-Dirac fermion detailed in the new study is a strange beast of ...
