A dialogue between Giuseppe Mussardo and Chiara Sabelli about the history of quantum mechanics, retracing the fundamental milestones, key figures, and most significant moments of one of the greatest ...

He also introduced the Dirac equation, combining Einstein’s special relativity with quantum mechanics, which predicted the existence of positrons (antiparticle of the electron) and antimatter in ...

Semi-Dirac fermions, massless in one direction and massive in another, were discovered in ZrSiS crystals, offering exciting ...

Dirac's thinking on this point hasn't restored ... scalar field in addition to the spacetime metric. These so-called Einstein-aether theories effectively assert the existence of a preferred ...

The Dirac equation had a sting in its tail ... and is instead explained by Einstein’s general theory of relativity as the warping of space-time – a very different kettle of fish.

It might be possible to probe a close analogue of zitterbewegung by recreating the mathematics of Dirac's equation in a quantum wire. Dirac's equation has an infinite number of solutions with ...
