It distorts the cell structure, decreasing it from the equilibrium volume and resulting in jagged energy vs. volume curves, cf. Figures 1 and 2. In this article, the computational origin of this is briefly discussed, and then solutions for correcting the Pulay stress. It is important to note that problems due to the Pulay stress can often be neglected if only volume-conservi...")
