A particularly exciting aspect of condensed matter physics is that we know the underlying physical rules for all condensed matter systems. Along with almost everything we interact with, condensed matter systems are made up of nuclei and electrons that interact via the Coulomb interaction. There is one universal set of rules, which result in many different behaviors that we see in our world. The tricky part is getting from the basic interactions of nuclei and electrons to that variety of behavior.

We perform highly accurate quantum simulations of many particles, particularly for realistic models of materials. In doing this, we use both small and large computational resources. We perform large calculations using leadership-class as well as using more traditional analytic methods. We also use data science techniques to better understand these simulations and the physics that emerges from collections of nuclei and electrons.
