Consider the following statements about the Hartree-Fock method and decipher if they are True (T), False (F) or indeterminable (i.e. more information is needed) The wavefunction consists of a single Slater determinant → this is (T, For l) It includes the exchange energy approximately → this is (T, For l) It includes exchange which only occurs between electrons of opposite spin → this is (T, For l) Due to the electron-electron interactions the computer time scales as a function of the number of basis functions to the power of 4 → this is (T, For l) A spin-polarized calculation on a material with an odd number of electrons will result in spin orbitals that have the same energy and spatial wavefunction. → this is (T, F or l) A single determinant wavefunction is a correlated wavefunction. → this is (T, F or l) The two-electron contributions to the energy for a pair of electrons with opposite spin is equal to (Jij). → this is (T, F or l)
Consider the following statements about the Hartree-Fock method and decipher if they are True (T), False (F) or indeterminable (i.e. more information is needed)
The wavefunction consists of a single Slater determinant → this is
(T, For l)
It includes the exchange energy approximately → this is
(T, For l)
It includes exchange which only occurs between electrons of opposite spin → this is
(T, For l)
Due to the electron-electron interactions the computer time scales as a function of the number of basis functions to the power of 4 → this is
(T, For l)
A spin-polarized calculation on a material with an odd number of electrons will result in spin orbitals that have the same energy and spatial wavefunction. →
this is
(T, F or l)
A single determinant wavefunction is a correlated wavefunction. → this is
(T, F or l)
The two-electron contributions to the energy for a pair of electrons with opposite spin is equal to (Jij). → this is
(T, F or l)
