- TL;DR Summary
- A little help with a two-particle hamiltonian

Hello, I'm working on a project. I need to understand every equation in a paper.

I need to calculate the spatial derivative of G (d/dR), a two-particle Hamiltonian. However, G is a function of P- the density matrix and P is a function of R. Is it a "special derivative"?

Here is the attached paper. <Moderator's note: deleted for copyright reasons>

thank you very much,
