WebThe Pulay stress is often nearly isotropic, and tends to result in an underestimate of the equilibrium volume. Pulay stress can be reduced by increasing the energy cutoff. Another … WebHow to calculate the Pulay stress The Pulay stress shows only a weak dependency on volume and the ionic configuration. It is mainly determined by the composition. The …
Peter Pulay (born September 20, 1941, in Veszprém, Hungary) is a theoretical chemist. He is the Roger B. Bost Distinguished Professor of Chemistry in the Department of Chemistry and Biochemistry at the University of Arkansas, United States. One of his most important contributions is the introduction of the gradient method in quantum chemistry. This allows the prediction of the geometric structure of a molecule using computatio… WebJul 2, 2024 · The Pulay Stress (named for Peter Pulay) is an error that occurs in the stress tensor obtained from planewave density functional theory calculations due to the ...
WebThe Pulay stress is often nearly isotropic, and tends to result in an underestimate of the equilibrium volume. Pulay stress can be reduced by increasing the energy cutoff. Another way to mitigate the effect of Pulay stress on the equilibrium cell shape is to calculate the energy at different lattice vectors with a fixed energy cutoff.
