Generalized Hartree-Fock Theory and the Hubbard Model
Volker Bach, Elliott H. Lieb, Jan philip Solovej
The familiar unrestricted Hartree-Fock variational principle is generalized to include quasi-free states. As we show, these are in one-to-one correspondence with the one-particle d…
The Hubbard Model: Some Rigorous Results and Open Problems
Elliott Lieb
Paper: cond-mat/9311033 The Hubbard model of interacting electrons, like the Ising model of spin-spin interactions, is the simplest possible model displaying many ``real world'' fe…
There are No Unfilled Shells in Hartree-Fock Theory
V. Bach, E. H. Lieb, M. Loss +1
Hartree-Fock theory is supposed to yield a picture of atomic shells which may or may not be filled according to the atom's position in the periodic table. We prove that shells are…
Uniform Density Theorem for the Hubbard Model
E. H. Lieb, M. Loss, R. J. McCann
A general class of hopping models on a finite bipartite lattice is considered, including the Hubbard model and the Falicov-Kimball model. For the half-filled band, the single-parti…
