Quantum Mechanics.
Find the energies, degenerations and wave functions for the first
three energy levels (ground state
and first two excited states) of a system of two identical
particles with spin , which move in a
one-
dimensional infinite well of size .
Find corrections of energies to first order in if an attracting potential of contact is added.
Show that in the case of "spinless" fermions, the previous perturbation has no effect.
Step by step process with good handwriting, please. It can be hard to read the answer sometimes.
Thank you a lot.

In this optional assignment you will find the eigenfunctions and eigenenergies of the hydrogen atom using an operator method which involves using Supersymmetric Quantum Mechanics (SUSY QM). In the SUSY QM formalism, any smooth potential Vx) (or equivalently Vr)) can be rewritten in terms of a superpotential Wix)l (Based upon lecture notes for 8.05 Quantum Krishna Rajagopal at MIT Physics II as taught by Prof Recall that the Schroedinger radial equation for the radial wavefunction u(r)-r Rfr) can be rewritten...
