| Feb 10, 2021 at 12:45 | comment | added | S R Maiti | AFAIK, Fermi correlation is the correlation between electrons of parallel spin, and Coulomb correlation is the correlation between any two electrons (cf. the classical Coulomb repulsion). They are both parts of dynamic correlation. Static correlation is when one electron configuration (Slater determinant) is not good enough to describe the system, due to energy levels coming close together, becoming nearly degenerate. That has nothing to do with Fermi or Coulomb correlation imo. | |

We hope to see much more of you in the future !!! I've edited your question slightly since we have a policy to ask just one question per post. You're welcome to ask the second question as another post if you'd like! | |
