On Relative Bounds for Interacting Fermion Operators
Volker Bach, Robert Rauch
We consider a Hubbard model with nearest neighbor interaction on a discrete -dimensional torus of length around its Hartree-Fock ground state and derive relative bounds of t…

Orthogonalization of fermion k-body operators and representability
Volker Bach, Robert Rauch
The reduced k-particle density matrix of a density matrix on finite-dimensional, fermion Fock space can be defined as the image under the orthogonal projection in the Hilbert-Schmi…
