In a recent study published in Materials Advances, Ryuhei Naito and colleagues discovered a method enabling selective observation of the Dirac electrons in materials. Using electron spin resonance ...

In 1928, Paul Dirac's relativistic quantum mechanics led to a formal understanding that an electron has two internal quantum mechanical degrees of freedom — electric charge and spin. This spin ...

Observing the effects of special relativity doesn't necessarily require objects moving at a significant fraction of the speed of light. In fact, length contraction in special relativity explains how ...

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 ...

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 ...

Conventional quantum mechanics didn't have such transitions, and Dirac's relativistic Schrödinger ... then are absorbed by the 1S electron state, which has spin 1/2. Accounting for the two ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...
