Developing Consistent Models for Matter in Extreme Conditions*

The extreme densities and temperatures accessible on modern experimental facilities alter the electronic and ionic structure of materials, leading to changes in state and transport properties that inform both simulations and the interpretation of experimental data. This talk will describe ongoing efforts to generate a comprehensive set of consistent state and transport data from a single atomic model whose electrons and ions respond self-consistently to changes in local material conditions. This approach ensures that equations of state, transport properties, and diagnostic signatures are mutually consistent. Such consistency can help to constrain simulations and may improve the reliability of data interpretation from complex experiments.
