摘要：

The concept of implicit exchange-correlation energy functionals [optimized potential method (OPM)] is applied to the helium and neon dimers. Using the lowest order correlation functional obtained within Kohn-Sham perturbation theory we find energy surfaces in reasonable quantitative agreement with the exact results, thus demonstrating that the OPM allows a seamless description of van der Waals bond systems.
