In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. In its free form, or including electromagnetic interactions, it describes all spin-1 ⁄ 2 massive particles, called "Dirac particles", such as electrons and quarks for which parity is a symmetry.
Die Dirac-Gleichung ist eine grundlegende Gleichung der relativistischen Quantenmechanik. Sie beschreibt die Eigenschaften und das Verhalten eines fundamentalen Fermions mit Spin 1/2 (zum Beispiel Elektron, Quark).
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. Since these are matrices ...

In this section we will describe the Dirac equation, whose quantization gives rise to fermionic spin 1/2 particles. To motivate the Dirac equation, we will start by studying the appropriate representation of the Lorentz group.

The Dirac equation is rightly regarded as one of the great monuments of modern physics. There is considerable formalism involved in mastering it, but it is an essential part of relativistic quantum mechanics, and we will take it one step at a time. 2. The Dirac Equation.
17. März 2023 · The Dirac equation is the foundation of the theory of particles with half-integral spin ($ \dfrac {1} {2} $, $ \dfrac {3} {2} $, $ \dfrac {5} {2} $, etc.), i.e., fermions that obey the Fermi statistics.
