Fig. 4: Estimated sensitivity indices and cluster interactions of cluster decompositions truncated at pairs and triplets.
From: The cluster decomposition of the configurational energy of multicomponent alloys
a Cluster sensitivity indices of two fitted CrCoNi CDs (one including only pairs, and another including pairs and triplets) sorted by cluster diameter. Effective (total) cluster sensitivity indices are shown with solid (translucent) colors. b Nearest-neighbor cluster interactions as two-dimensional arrays. Each entry of the array represents the interaction energy between the corresponding nearest neighbor species.
