EQSE diagonalization of the Hubbard model

Creators

Description

The application of enhanced quasi-sparse eigenvector methods (EQSE) to the Hubbard model is attempted. The ground state energy for the 4 x 4 Hubbard model is calculated with a relatively small set of basis vectors. The results agree to high precision with the exact answer. For the 8 x 8 case, exact answers are not available but a simple first order correction to the quasi-sparse eigenvector (QSE) result is presented
