Finding ground state

  1. Dec 13, 2011 #1

    If I have the Hamiltonian: [itex] H=(1/2)p^2+(1/24)\lambda(x^2-v^2)^2[/itex] what is the best way to find the ground state wave functions [itex] \psi(x) [/itex]. I was thinking this sort of looks like the harmonic osscilator, so maybe a clever change of variables could do the trick? or some form of perturbation perspective?

    Enter the key words
    high order expansion anharmonic oscillator
    into http://scholar.google.com to get a lot of references.
