✦ Synopsis

The effect of dynamical exchange interactions on the dielectric function of a two-dimensional electron gas is studied using a variational approach. Exchange effects are introduced via the local-field correction. The variationally obtained local-field factor is compared to the earlier perturbative result to first order in the electron -electron interaction.

We find approximate expressions for the spin-dependent local field correction functions in a twodimensional spin polarized electron gas by considering their limiting behavior at small and large wavevectors and sum rules. Using these constructed local field functions, we analyze the effective electro
