What Does HPHF Stand For?

HPHF stands for Half Projected Hartree Fock Model

HPHF, or Half Projected Hartree Fock Model, is a computational method in quantum chemistry that combines elements of Hartree-Fock theory with projection techniques. This model aims to improve the accuracy of electronic structure calculations by incorporating both correlation effects and the constraints of symmetry in the wave functions. HPHF is particularly useful in the study of complex molecular systems, where traditional methods may fall short in capturing the subtle interactions between electrons.
