Lower Bound on the Hartree-Fock Energy of the Electron Gas
David Gontier, Christian Hainzl, Mathieu Lewin
The Hartree-Fock ground state of the Homogeneous Electron Gas is never translation invariant, even at high densities. As proved by Overhauser, the (paramagnetic) free Fermi Gas is…

The BCS critical temperature in a weak external electric field via a linear two-body operator
Rupert L. Frank, Christian Hainzl
We study the critical temperature of a superconductive material in a weak external electric potential via a linear approximation of the BCS functional. We reproduce a similar resul…

On the correlation energy of interacting fermionic systems in the mean-field regime
Christian Hainzl, Marcello Porta, Felix Rexze
We consider a system of interacting fermionic particles in three dimensions, confined in a periodic box of volume , in the mean-field scaling. We assume that the intera…
