The Dirac equation, like the Klein–Gordon equation, possesses solutions with negative energy, which, in the framework of wave mechanics, leads to diﬃculties (see below). To prevent transitions of an electron into lower lying states of negative en-ergy, in 19306 Dirac postulated that the states of negative energy should all be occupied.

The meaning of the simple looking Dirac equation is not as simple as we might think. Since its first formulation, its meaning has changed from a relativistic wave equation for an electron to a classical field equation from which an electron-positron quantum field

The fifth term is the so called Darwin termwhich we said would come from the Dirac equation; and now it has. For a free particle, each component of the Dirac spinor satisfies the Klein-Gordon equation. This … Dirac equation. In particle physics, the Dirac equation is a relativistic wave equation formulated by British physicist Paul Dirac in 1928. It describes fields corresponding to elementary spin-½ particles as a vector of four complex numbers, in contrast to the Schrödinger equation which described a … A Dirac-delta function, $\delta(x)$, is strictly speaking not a function. It is a distribution and the equation you have above is actually a defining property of the Dirac-delta function - it only makes mathematical sense under an integral.

momentum tensor, and its bizarre equation of motion for the electron (the Lor entz-Dirac equation, LDE). This work went on to explain and predict the existence of antimatter; the idea that every particle has a mirror-image antiparticle. It tells of an aged scholar who has devoted his life to the study of Spinoza’s great work, Ethics.

The Dirac equation is the relativistic description of an electron. The non-relativistic description of an electron is described by the Pauli-Schroedinger equation. The non-relativistic electron has two spin states and we say that it is a two component equation. momentum tensor, and its bizarre equation of motion for the electron (the Lor entz-Dirac equation, LDE). This work went on to explain and predict the existence of antimatter; the idea that every particle has a mirror-image antiparticle.

Specific solutions may have a different form, but the physics seems to be the same.
