Homework Help: Momentum term to be expanded in dirac gamma matrices

  1. Sep 22, 2012 #1
    1. The problem statement, all variables and given/known data

    I need help to expand some matrices

    2. Relevant equations

    [tex]\pi = \frac{\partial \mathcal{L}}{\partial \dot{q}} = i \hbar \gamma^0[/tex]

    3. The attempt at a solution

    How do I expand

    [tex]i\hbar \gamma^0[/tex]

    the matrix in this term, I am a bit lost. All the help would be appreciated!

    That looks odd. Can you give us the Lagrangian that you're starting with?

    It has been a while since I dabbled with Dirac matrices... factoring gamma zero is simply 1.

    DUH to me.
