论文摘要
在极度密度和压力下对物质进行实验的准确解释是一个众所周知的挑战。在最近的作品[T.〜Dornheim等人，自然通讯中。 （印刷），Arxiv：2206.12805]，我们引入了一种正式精确的方法，该方法允许在没有任何模型假设或模拟的情况下提取任意复杂材料的温度。在这里，我们为这种方法提供了更详细的介绍，并分析了实验噪声对提取温度的影响。特别是，我们将我们的方法广泛地应用于合成散射数据，以及在广泛的温度和波数中的实验测量。我们预计我们的方法将对一系列应用，包括惯性限制融合，实验室天体物理学以及高度准确的状态数据库的汇编。
The accurate interpretation of experiments with matter at extreme densities and pressures is a notoriously difficult challenge. In a recent work [T.~Dornheim et al., Nature Comm. (in print), arXiv:2206.12805], we have introduced a formally exact methodology that allows extracting the temperature of arbitrarily complex materials without any model assumptions or simulations. Here, we provide a more detailed introduction to this approach and analyze the impact of experimental noise on the extracted temperatures. In particular, we extensively apply our method both to synthetic scattering data and to previous experimental measurements over a broad range of temperatures and wave numbers. We expect that our approach will be of high interest to a gamut of applications, including inertial confinement fusion, laboratory astrophysics, and the compilation of highly accurate equation-of-state databases.
