# Local Density Functional and Strong On-Site Correlations: The Electronic Structure of La_{2}CuO_{4}

Chapter

## Abstract

The density functional (DF) theory has been a most successful theoretical method for describing ground state properties in solid state physics since the beginning of seventies [1, 2]. An enormous amount of applications of the local density approximation (LDA) to the DF can be found in the literature for the description of a wide range of phenomena in a wide range of materials (see e.g. references within Refs. [1, 2] and reviews [3, 4]). Unfortunately the class of materials where the LDA does not work properly is also growing rapidly including those with the most startling physical properties.

*U*reported in the literature, because of the different, often only implicitly assumed conventions which are used. All values obtained by constrained-LDA calculations involving atomic-sphere (muffin-tin) approximation should be identified with*screened*Slater monopole integral*F*^{0}_{eff.}So we do, see Appendix. The diagonal values of Coulomb interaction*U*_{mm}, m =*x*^{2}—*y*^{2}, 3*z*^{2}—*r*^{2},*xy, etc*, are, however, different. In terms of Racah*A, B*and*C*parameters they read:*U*_{d}=*F*^{0}_{eff.},*A*+ 7/5*C*, and*U*_{mm}= A + 4*B*+ 3*C*. As an example,*U*_{d}= 7.42 eV in Ref. [26] and*U*(*d*_{x}^{2}−_{y}^{2}) = 8.96 eV in Ref. [20] are in fact the same. Of course, values of*B*and*C*have to be known. The authors of references used in this example did not confuse that matter, but it seems that ambiguity about these values exists in the literature.Google Scholar - [28]V.I.
