Quantum, matrix and momentum operator

  1. Mar 21, 2014 #1
    1. The problem statement, all variables and given/known data

    Write out matrix representation of P.

    Also, do P|ψ>

    2. Relevant equations

    ψ=ψ0 + 2ψ1

    ψ0=(1/∏)1/4 exp(- u2/2)

    ψ1=(1/∏)1/4 √2 exp(- u2/2)

    P= 1/(i*∏) d/du

    3. The attempt at a solution

    I've no clue what to do. If I had a ψm ψn I would, but what do I do with just ψ0 ψ1?

    What would you do in the former case?
