Improved Hartree--Fock resummations and spontaneous symmetry breaking
Claudio Destri, Andrea Sartirana
The standard Hartree--Fock approximation of the invariant model suffers from serious renormalization problems. In addition, when the symmetry is spontaneously broken,…

The renormalized and Renormalization-Group invariant Hartree-Fock approximation
Claudio Destri, Andrea Sartirana
We study the renormalization problem for the Hartree--Fock approximation of the invariant model in the symmetric phase and show how to systematically improve the corre…
