This application implements the Hubbard-I solver in triqs using the lightweight diagonalization routine which come with triqs/atom_diag.
Requires a working TRIQS installation with a matching major version number.
The Solver comes with the same interface as, e.g., the cthyb solver. More information on how to use the solver can be found in the documentation.
TRIQS/hubbardI is supported by the Flatiron Institute, a division of the Simons Foundation.
