1. The problem statement, all variables and given/known data Find the ground state energy of a particle restricted to move in one dimension subject to the potential in the attachement using perturbation theory. 2. Relevant equations Yo = (2/a)1/2 sin(nπx/a) 3. The attempt at a solution I'm not sure how to account for the potential since there are two wells. My setup right now using braket notation is E = 2<Y|Y> + <Y|Vo|Y> where Y is the wavefunction Yo = (2/a)1/2 sin(nπx/a) Can I get some feedback as to if I am headed in the right direction or how to get there if I am not? Thank you.
