A new approach to correlation energies of inhomogeneous many-electron systems
We generalize the uniform-gas correlation energy formalism of Singwi, Tosi, Land and Sjölander to the case of an arbitrary inhomogeneous many-particle system. For jellium slabs of finite thickness with a self-consistent groundstate electron density profile, our numerical results for the correlation energy agree well with diffusion Monte Carlo results. For a helium atom we also obtain a good cor...
متن کاملLocal correlation energies of two-electron atoms and model systems
We present nearly local definitions of correlation energy density, and its potential and kinetic components, and evaluate them for several two-electron systems. This information should provide valuable guidance in constructing better correlation functionals than those in common use. In addition, we demonstrate that the quantum chemistry and the density-functional definitions of the correlation ...
متن کاملRigorous description of exchange-correlation energy of many-electron systems.
With the eigenfunctional theory, we study a general interacting electron system, and give a rigorous expression of its ground state energy, which is composed of two parts: one part is contributed by the non-interacting electrons, and the other one is represented by the correlation functions that are controlled by the electron correlation. Moreover, according to the rigorous expression of the gr...
متن کاملMany Electron Atoms: Ionization Energies of Transition Elements
The paper introduces a theoretical model aimed to calculate the ionization energies of many electron atoms and their ions. The validity of the model, which implements the statistical formulation of the quantum uncertainty to infer a simple formula of ionization energy, has been already proven in a previous paper comparing systematically experimental and calculated values for elements with atomi...
متن کاملAn inhomogeneous and anisotropic Jastrow function for non-uniform many-electron systems
Quantum Monte Carlo simulations of interacting electrons in solids often use Slater-Jastrow trial wave functions. The Jastrow function takes into account correlations between pairs of electrons. In simulations of solids, it is common to use a Jastrow function which is both homogeneous and isotropic. The use of a homogeneous and isotropic Jastrow factor is questionable in applications to systems...
