QMC-HAMM aims to simulate the detailed motion of electrons in materials. From these simulations, researchers then build up coarse-grained pictures of materials ranging from the interior of Jupiter, atomic-sized defects that emit and receive light, to ionic conductors to make the next highly efficient battery. INCITE resources will be used to obtain an unprecedentedly detailed picture of the motion of electrons, making our models more accurate, quantitative, and predictive. The data will be used by other researchers to improve their pictures of materials, and the models will be used to design and control the behavior of materials.
