Constraining density functional approximations to yield self-interaction free potentials
Constraining density functional approximations self-interaction free potentials
2011/8/18
Abstract: Self-interactions (SIs) are a major problem in density functional approximations and the source of serious divergence from experimental results. Here, we propose to constrain the effective l...
Competing with oneself: Introducing self-interaction in a model of competitive learning
Introducing self-interaction competitive learning phase diagrams
2010/4/1
A competitive learning model was introduced in Ref. 1 (A. Mehta and J. M. Luck, Phys. Rev. E 60, 5, 1999), in which the learning is outcome-related. Every individual chooses between a pair of existing...
Polarizibilities as a test of localized approximations to the self-interaction correction
Density Functional Theory Self-Interaction Correction Optimized Effective Potential SIC-Slater approximation Static polarizability
2010/4/8
We present applications of the recently introduced ``Generalized SIC-Slater'' scheme which provides a simple Self-Interaction Correction approximation in the framework of the Optimized Effective Poten...
