Interatomic forces in condensed matter 2004
NettetIn Condensed Matter Physics, the task of obtaining different mechanical properties of materials, simulated atomistically with a large number of atoms under ab initio methods, is an almost prohibitive one, in terms of computational effort with the current computer architectures. It might even at times be impossible.

In all such programs there is some physical model of the inter-atomic forces, which may be based on something as simple as a pair interaction, such as the Lennard-Jones model, or as … sarthadonfNettetOur simulations indicate that the interstitials migrate via two distinct mechanisms: through hops between interstitial sites and through exchanges with lattice atoms. We extract activation energies for both of these mechanisms and show how the temperature dependence of the total diffusion coefficient deviates from Arrhenius behaviour. sarthac.gov.inNettet14. mai 2024 · The energy and structural parameters were obtained for all forms of the carbonyl complex of osmium Os3(CO)12 with D3h and D3 symmetries using density functional theory (DFT) methods.
