Equivariant graph neural network surrogates for predicting the properties of relaxed atomic configurations
Jamie Holber, Siddhartha Srivastava, Krishna Garikipati
Density functional theory (DFT) calculations determine the relaxed atomic positions and lattice parameters that minimize the formation energy of a structure. We present an equivari…

Inference of phase field fracture models
Elizabeth Livingston, Siddhartha Srivastava, Jamie Holber +2
The phase field approach to modeling fracture uses a diffuse damage field to represent a crack. This addresses the singularities that arise at the crack tip in computations with sh…

Physics- and data-driven Active Learning of neural network representations for free energy functions of materials from statistical mechanics
Jamie Holber, Krishna Garikipati
Accurate free energy representations are crucial for understanding phase dynamics in materials. We employ a scale-bridging approach to incorporate atomistic information into our fr…
