Homework Statement
I am given the hamiltonian, where [tex]H^{^}_{0}[/tex] is that of the harmonic oscillator and the perturbation is (lambda)*(h-bar)*(omega)*[(lowering operator)^2 + (raising operator)^2]. I am asked to find the ground state, second-order approx. energy value.
Homework Equations
Second order eigenenergy equation.
The Attempt at a Solution
I have written out the whole hamiltonian. Do I need to expand the lowering-raising operators in terms of n? I am a bit lost on what to plug into the second order equation for the two wave functions m and n (which sandwich the Hamiltonian operator).
