The Hubbard model in the singlet subspace: a symmetry-entangled
In this talk I shall present a new approach to the determination of
many-body wave-functions respecting the symmetries of a microscopic
hamiltonian such as the Hubbard model. This approach will first be
introduced, and then tested against numerical simulations where available.
In a second part the spin, charge, and pairing properties entailed in such
symmetry-entangled wave-functions will be discussed.
