Self-consistent equations including exchange
WebFrom a theory of Hohenberg and Kohn, approximation methods for treating an inhomogeneous system of interacting electrons are developed. These methods are exact for systems of slowly varying or high density. For the ground state, they lead to self-consistent equations analogous to the Hartree and Hartree-Fock equations, respectively. In these … WebApr 11, 2024 · Table 1 showed the descriptive statistics and correlations of measured variables. According to the mean value of the ideal self and enjoyment (M ideal self = 3.15, SD = 0.76; M enjoyment = 3.18, SD = 0.59), students, in general, possessed a moderate level of aspirations and enjoyment of L2 integrated writing.According to the correlational …
