Calculate the expectation value of V from Ehrenfest's theorem

    1. The problem statement, all variables and given/known data
    I have a general question how I calculate the expectation value of V (potential energy) with Ehrenfest’s theorem. Do I have to integrate d<p>/dt with respect to d<x>. Also if the potential is symmetric (even) would that mean the expectation value of the potential is 0?

    2. Relevant equations

    3. The attempt at a solution

    Can you explain your notation ? In particular "integrate ... with respect to d<x>" ?

    See the reference 2 in google Ehrenfest (you did google, didn't you ?).

    By the way, your post violates the PF rules/guidelines and will probably be removed ...
