Wigner Matrix or Wigner D-Matrix?

  1. Nov 23, 2011 #1
    Hello guys,

    I'm reading the attached article, and I found there the Wigner Matrix, the first equation in the second page... is that the Wigner D-Matrix? I really got lost in that. It doesn't look like the Wigner D-Matrix I see everywhere, and it's not the so-called random matrix... anyone knows what that really is? please explain!

    Thank you for any efforts.

    It's not the Wigner D-matrix from the representation theory of SU(2), but the matrix of the Wigner function from quantum transport equation.

    Thank you for your reply.

    Can that be found in some book? I don't know where to read about that.
