If we have 2 particles in ground state in an infinite quantum well of length L (one-dimetion). Suppose then that the unperturbed energy is two times the ground energy of only one particle in an infinite qunatum well of length L.
Then I want to use first order perturbation theory to find the perturbed energy if the perturbation is A*d(x2-x1) (diracs-delta function), interaction between the particles or something, where A is a constant.
How do I construct the wave equation for this system en how do I calculate the perturbation?
I have tried with various linear combinations with no convincing success.
