- Homework Statement
- In an infinite potential well, two small constant perturbations \epsilon are added in the two opposite corners of the well in an infinitesimal extent (\delta). In what order of \epsilon the correction to the ground state energy would be? See the attached file.

- Relevant Equations
- <psi|Hp|psi>=E1

If I calculate ## <\psi^0|\epsilon|\psi^0>## and ## <\psi^0|-\epsilon|\psi^0>## separately and then add, the correction seems to be 0 since ##\epsilon## is a constant perturbation term.

SO how should I approach this? And how the Δ is relevant in this calculation?
