New results for the structure of certain warm dense matter states

The dynamic and static structure factors contain a wealth of information about the state and properties of a physical system. The structure of a system relates directly to its equation of state, collective modes, stopping power and relaxation processes. Since x-ray and particle scattering are extremely important experimental tools to diagnose warm dense matter, theoretical predictions of the structure have become one of the best modes of comparison between theory and experiment in the warm dense matter regime. We give an overview of state of the art theoretical methods to calculate the structure of warm dense matter in equilibrium and non-equilibrium. Results are given for such states as created in recent experiments. Limits of the current theories and possible future developments are discussed.
