What Does UHFS Stand For?

UHFS stands for Unrestricted Hartree Fock Slater

UHFS, or Unrestricted Hartree Fock Slater, refers to a quantum chemical method used for the approximation of the electronic structure of many-electron systems. This approach extends the traditional Hartree-Fock method by allowing for different spin states in the descriptions of electrons, thereby accommodating systems with unpaired electrons or open-shell configurations. By utilizing Slater determinants, UHFS provides a more flexible framework for representing electron correlations while maintaining computational efficiency, making it a valuable tool in theoretical and computational chemistry for studying various chemical systems.
