Dear Prof. Tran,
I would like to read more about this subject, but, unfortunately, your
link gave me a message like : " Wikipedia does not have an article with
this exact name. "
Please*,* could you suggest another non-specialist reference like
wikipedia ?
Thank you,

Hi,
DFT+U is a cheap but rather rough approximation of HF.
Beside this, there is also the difference that in DFT+U, the Coulomb
operator is attenuated in order to account for the screening due to
correlation. In HF, no correlation is included.
In hybrids, the screening is included by using only ~

Hi,
all these methods are somehow based on the Hartree-Fock method,
which is (partially) free of self-interaction error.
The SIE with LDA/GGA is particularly
DMFT trying to model?
Cheers

Subject: [Wien] Hartree-Fock and the Hubbard Model
Dear WIEN2k community,
From what I understand the Hubbard Model is to calculate the electronic
repulsion inside the orbitals, specially in the 3d and 4f.
Is it an approximation for the Hartree Fock exchange?
If this is the
no it's Coulomb repulsion (diagonal)

If this is the case then it can be better calculated exact-exchange functionals
