Dirac matrix

Dirac matrix

[di′rak ′mā‚triks]
(quantum mechanics)
Any one of four matrices, designated γμ(μ = 1, 2, 3, 4), each having four rows and four columns and satisfying γμγv+ γvγμ= δμ v , where δμ v is the Kronecker delta function, which matrices operate on the four-component wave function in the Dirac equation. Also known as gamma matrix.

Here [GAMMA] is the any Dirac matrix, and [G.sub.[mu]v] is the gluon field strength tensor, respectively.
For this case the eigenvalues of the Dirac matrix [[gamma].sub.0] define the wave numbers of the waves traveling in the anisotropic medium.
