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 ...

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 ...

You probably don't think about the Dirac equation on an average day, but it describes just about everything that happens to you. People hate losing money about twice as much as they love making it: It ...
