Just full disclaimer: I am a first year physics graduate student with very little experience in physics research. I would like to write to develop a toy model to teach myself a bit about spin interactions between two copper ions with nuclear spin and electron spin.
I am wondering what resources, books, numerical recipes, papers, code, etc, should I be thinking about?
I know it's very open-ended. I just know that from first principles one should write the hamiltonian of said system. I also know this is a hard problem to try to compute so that's why I am here, to seek guidance.
