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.

formulae (“The Dirac Equation”, Equations 118, The key piece of physics that we missed is that spin 1/2 particles are fermions, meaning that they obey Fermi-Dirac statistics with the quantum state picking up a minus sign upon the interchange of any two particles.

Se hela listan på en.wikipedia.org The Dirac equation is one of the two factors, and is conventionally taken to be p m= 0 (31) Making the standard substitution, p !i@ we then have the usual covariant form of the Dirac equation (i @ m) = 0 (32) where @ = (@ @t;@ @x;@ @y;@ @z), m is the particle mass and the matrices are a set of 4-dimensional matrices. 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. 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 field of only one complex value.

Where, 𝜓=𝜓 (x,t) is the electron wave function. M is the electron mass at rest.

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

Dirac equation is the relativistic extension to Shrodinger's equation. Instead of considering classical energy conservation we consider E^2=m^2*c^4+p^2*c^2 And plug the quantum operators instead of E and p We get: Div^2 - 1/c^2*d^2/dt^2=m^2*c^2/h-bar^2 Which is the Dirac equation.

velocity solution of Dirac equation is taken as the definition of elementary particles. Leptons, mesons and baryons appear in results as the newly defined

The fifth term is the so called Darwin termwhich we said would come from the Dirac equation; and now it has.

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.

It is the solution to equation: m is the ‘mass’ of the particle. is the solution of the wave equation: ie a linear combination of the equation: The ‘delta’ is na ‘operator’. Dirac argued that the hole should be a proton, which is positive.
