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 ...

A team of researchers has now observed something physicists had only theorized: a quasiparticle that behaves like it has mass ...

Scientists have observed a quasiparticle that exhibits a very odd behavior: it appears to have mass, but only while moving in ...

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 ...

According to Albert Einstein's theory of special relativity ... Shao explained. Semi-Dirac fermions were first theorized in 2008 and 2009 by several teams of researchers, including scientists ...

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 ...
