Project description
 

The description of the higher-dimensional Hubbard model in terms of pair-based wavefunctions is investigated. Possible extensions of the pairing correlations as introduced in the Bethe ansatz for the integrable Richardson-Gaudin model are considered for a possible use in a numerical implementation of a variational method for the 2D Hubbard model.
