Techniques for Phonon Superposition Modeling of Shocks and Waves in Solids Research Area 3: Mathematics - Numerical Analysis
Abstract
A new approach for modeling phonons will be developed and the modeling errors will be estimated and determined numerically. The approach targets the study of non-equilibrium processes and is based on fundamental principles of quantum field theory as applied to phonons. The new computational methods will be developed and their solutions compared to solutions from an equilibrium-based approach which is representative of methods based on the Boltzmann Transport Equation. The possible advance enabled by capability of studying nonequilibrium phonons is the modeling of mechanical processes such as shock loading at mesoscopic length scales built-up from nanoscopic information.
