What Does BHF Stand For?

BHF stands for Broken Symmetry Hartree Fock

BHF, or Broken Symmetry Hartree Fock, is a computational method used in quantum chemistry and many-body physics to describe interacting fermionic systems, particularly in cases where traditional symmetries are not preserved. It extends the Hartree-Fock approach by allowing for the explicit breaking of certain symmetries, such as spin or particle-hole symmetry, thereby providing a more accurate representation of ground and excited states in correlated electronic systems. BHF is particularly valuable in the study of systems exhibiting strong correlations, such as those found in nucleons within atomic nuclei or electrons in strongly correlated materials.
