An international group of physicists has traced the origin of an electromagnetic interaction to the Dirac equation, a fundamental equation of quantum physics. The interaction couples the spin of the ...

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 ...

An important electronic property of graphene has been simulated for the first time using ultracold atoms. The experiment was carried out by physicists in Switzerland, who reproduced graphene’s ...

The father of antimatter was the remarkable English physicist Paul Dirac (1902-1984), considered by many to be the greatest British theorist since Sir Isaac Newton. His research marked the first time ...
