WebJan 24, 2024 · We report first-principles molecular dynamics study of the equation of state, structural, and elastic properties of CaAl 2 Si 2 O 8 glass at 300 K as a function of pressure up to 155 GPa. Our results for the ambient pressure glass show that: (1) as with other silicates, Si atoms remain mostly (> 95%) under tetrahedral oxygen surroundings; … A molecular dynamics simulation requires the definition of a potential function, or a description of the terms by which the particles in the simulation will interact. In chemistry and biology this is usually referred to as a force field and in materials physics as an interatomic potential. Potentials may be defined at many levels of physical accuracy; those most commonly used in chemistry are based on molecular mechanics and embody a classical mechanics treatment of particle-particle in… WebMay 2, 2024 · We describe the implementation of a computational scheme for estimating lattice thermal conductivities of ordered and disordered solids using the Einstein diffusion relationship and the energy moment, sampled from first-principles Born–Oppenheimer molecular dynamics employing density functional theory.
