A python implementation of Bethe ansatz in the Hubbard model by Lieb and Wu

The source code used for solving the Bethe equations for various potentials such as the inverse-square potential, inverse-sinh-squared potential and the delta potential. Ultimately, after a sensible Coulomb phase shift has been found, the code will be exploited to investigate the Coulomb system.
