Multiscale Analysis

Overview

We employ density function theory (DFT) computations to inform phase field models.  Specifically, we employ Bayesian statistics to estimate phenomenological Landau energy parameters and electrostrictive parameters.  We also employ global sensitivity analysis to quantify the relative influence of parameters on measured responses.
