Abstract
We introduce the near-held exchange method for calculating Hartree-Foc k exchange in time scaling near-linearly with system size. Benchmarks on polyglycine chains, water clusters, and diamond pieces show that mi crohartree accuracy and substantial speedups (up to 10x) over traditio nal calculations can be obtained for electrically insulating systems l arger than 300 atoms.
