Conventional quantum mechanics didn't have such transitions, and Dirac's relativistic Schrödinger equation (naturally called the Dirac equation) did not have such a hyperfine transition either, ...

Enter Ettore Majorana. In his 1937 paper 2, Majorana posed, and answered, the question of whether equations for spin-½ fields must necessarily, like Dirac's original equation, involve complex ...

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 ...

The British physicist Paul Dirac started the ball rolling in the late 1920s with his equation describing how relativistic electrons – and with it most other matter particles – behave.

Role of Massless Fermions and the Dirac Equation Due to the presence of Dirac cones, electrical conduction in these materials can be described by the movement of charge carriers, which are massless ...
