【 摘 要 】

We have developed an improved computational theory of condensed matter in the regime where T {le} T{sub Fermi}. Previous methods of calculating the equation of state (EOS) relied on interpolation between low-temperature (solid) and high-temperature (plasma) limits, or employed severe approximations. Recent theoretical and experimental developments have highlighted the need for accurate EOS and opacity data in the intermediate temperature range and offer the opportunity to test theoretical models. We describe our results for EOS and optical properties for temperatures up to 10{sup 6} K, and describe directions for future work.
