GTGetSU2Matrix

GTGetSU2Matrix[symmetry element]

gives the SU(2) matrix of a symmetry element.

Details and Options

  • The input of GTGetSU2Matrix can be of type symbol, matrix, quaternion, and Euler angles (compare GTSymbolQ, GTQuaternionQ or GTEulerAnglesQ).
  • See: W. Hergert, M. Geilhufe, Group Theory in Solid State Physics and Photonics. Problem Solving with Mathematica, chapter 2.

Examples

Basic Examples  (1)

First, load the package:

Even if the actual representation is not SU(2) GTGetSU2Matrix results in the corresponding 2x2 matrix.

Whereas GTGetMatrix gives the matrix in the actual representation.
