VoroTypes: automated enumeration of Voronoi cell topologies for structural identification of complex crystals in atomistic simulations
Emanuel A. Lazar, Chris H. Rycroft
VoroTypes enumerates, for an arbitrary crystal structure, the complete family of Voronoi cell topologies that can arise under small generic perturbations of atomic positions, and e…
Characterizing structural features of two-dimensional particle systems through Voronoi topology
Emanuel A. Lazar, Jiayin Lu, Chris H. Rycroft +1
This paper introduces a new approach toward characterizing local structural features of two-dimensional particle systems. The approach can accurately identify and characterize defe…
Identification of high-reliability regions of machine learning predictions in materials science using transparent conducting oxides and perovskites as examples
Evan M. Askanazi, Emanuel A. Lazar, Ilya Grinberg
Progress in the application of machine learning (ML) methods to materials design is hindered by the lack of understanding of the reliability of ML predictions, in particular for th…
Distribution of Topological Types in Grain-Growth Microstructures
Emanuel A. Lazar, Jeremy K. Mason, Robert D. MacPherson +1
An open question in studying normal grain growth concerns the asymptotic state to which microstructures converge. In particular, the distribution of grain topologies is unknown. We…
VoroTop: Voronoi Cell Topology Visualization and Analysis Toolkit
Emanuel A. Lazar
This paper introduces a new open-source software program called VoroTop, which uses Voronoi topology to analyze local structure in atomic systems. Strengths of this approach includ…
Roundness of grains in cellular microstructures
Frank H. Lutz, Jeremy K. Mason, Emanuel A. Lazar +1
Many physical systems are composed of polyhedral cells of varying sizes and shapes. These structures are simple in the sense that no more than three faces meet at an edge and no mo…
Geometric and topological properties of the canonical grain growth microstructure
Jeremy K. Mason, Emanuel A. Lazar, Robert D. MacPherson +1
Many physical systems can be modeled as large sets of domains "glued" together along boundaries - biological cells meet along cell membranes, soap bubbles meet along thin films, co…
Complete topology of cells, grains, and bubbles in three-dimensional microstructures
Emanuel A. Lazar, Jeremy K. Mason, Robert D. MacPherson +1
We introduce a general, efficient method to completely describe the topology of individual grains, bubbles, and cells in three-dimensional polycrystals, foams, and other multicellu…
