HPhi is a software package for solving quantum lattice models using the exact diagonalization method. It supports a wide range of quantum lattice models, including Hubbard, Heisenberg, and Kondo lattice models. HPhi can calculate ground state and excited state properties, as well as thermal averages using the thermal pure quantum (TPQ) state method.
