A generalized local approximation to the exchange potential
arXiv:chem-ph/9508001 · doi:10.1103/PhysRevB.52.16476
Abstract
A new method to obtain a local parameterization for the exchange term in the many--body electronic problem is presented. The approach amounts to the introduction of a coordinate dependent electron effective mass. Numerical results for metallic clusters in the jellium model are compared with other standard methods.
