Dirac gamma matrices | Dirac gamma matrix | gamma matrices

The Dirac matrices are a class of 4×4 matrices which arise in quantum electrodynamics. There are a variety of different symbols used, and Dirac matrices are also known as gamma matrices or Dirac gamma matrices. The Dirac matrices α_n may be implemented in a future version of the Wolfram Language as DiracMatrix[n], where n = 1, 2, 3, 4, or 5.
