Renormalization group methods for dynamics of spatially extended systems
… the macroscopic sharp interface limit of various phase field models of dendritic growth. We demonstrate the virtue of using coarse grained variables in simulations, as opposed to uniformly sampling the underlying continuous configuration. By coarse graining a system repeatedly, the 'perfect …

Development of stable operator splitting numerical algorithms for phase-field modeling and surface diffusion applications
… were used to create Allen-Cahn and Cahn-Hilliard phase field models. Individual terms of the conservation equations were approached by different methods using operator splitting techniques found in previous literature. In addition, dewetting of gold films due to surface diffusion was modeled to …

Accounting for temperature and local structure in atomistic calculations of interface free energies in metals
… temperature, especially for entropy stabilized phases such as liquids. I present methods for calculating location-dependent energies for solid-state interfaces and temperature-dependent free energies for solid/liquid interfaces using atomistic models. I demonstrate these methods on CuNbHe and …

Lithium-ion battery modeling using non-equilibrium thermodynamics
… Additionally, this modification also allows phase separating materials to be modeled directly using phase field models. This is especially useful for materials such as lithium iron phosphate and graphite, which are currently modeled using a fit open circuit potential and an artificial phase …
