Things to understand about the nuclear many-body problem

A snapshot of the nuclide chart

Auxiliary note to The nuclear many-body problem 🤯.

• Lots of things... (check small notebook)
• Exact meaning of multipole transitions (book, Stephen).
• How to extract the form factors once you have the wavefunctions.
• Why TF are states from 1 to A (i.e., the occupied ones) called hole states?
• Chapter 11 may be very important for your purposes (restoration of broken symmetries). Or maybe not.
• How tf do you measure the parity of a nucleus experimentally?
• Are boson expansion methods important for your calculation? Have they been used in other calculations recently?
• Would an interaction derived from a general potential and solved "exactly" automatically include collective effects? Hmmmm... If not, can I just get the ph-force from density-dependent HF? In any case, does it make sense to include HFB or RPA effects in your initial computation of the shells (like in the paper) if you are going to add the explicit pairing and ph terms to the hamiltonian later? I guess it does, but must think about it.
• Can Brückner G-matrix be used for 3-body interactions? Check this.
• For unbound states: how do you compute spectral functions/removal distributions from the wavefunctions?
• What exactly are you solving for in the RPA equations? You have to understand RPA better in general, and how it would be relevant to your approach. Can you "add it" to your hamiltonian? Furthermore, why tf is RPA called RPA?
• Appendix E.2, where THE FUCK does the first equation come from? This is ridiculous and the authors are stupid.
• What is no-core shell model? What are other "renormalization" schemes I can use instead of the G-matrix?
