comment four boson quantum system contact interaction
Ill stop doing that.I can list about 12 state kets and their energies for non interacting system and write the matrix in a diagonal form with those energies as eigenvalues and state kets as eigenvectors...but what good will that do? How can I form states of interacting system? This is my first many body problem so...what is exact diagonalization?

I have no idea how to begin solving this problem. Am I suppose to form some sort of diagonal matrix? What are the state kets?
