PALLAS predicted this complex transition pathway network for silicon. If you know how to read it, it is a roadmap that shows possible transition pathways between different structures. The tool developed by Zhu, Strobel, and Cohen correctly identified the lowest-energy transition pathway for silicon upon decompression from high pressure (thick black line). The structures in the four boxes show the different configurations of atoms along the transition path. The background colors indicate contours on the energy landscape. The points indicate stable and metastable structures of silicon with their size and color proportional to volume and energy, respectively. The composite of circles is similar to methods used in social networking analysis. Image provided courtesy of Timothy Strobel
