Expectation value at ground state

  1. May 17, 2013 #1
    I realise that at ground state of a harmonic oscillator the energy will be at zero.
    I'm assuming that the expectation value will also be at zero.

    Could someone confirm this & possibly explain just a little more.
    Thank you

    It is conventional to set the potential energy at equilibrium to zero, which means that the energy of the ground state is not zero, see http://en.wikipedia.org/wiki/Quantum_harmonic_oscillator

    Expectation value of what?
