论文摘要
对温暖的物质（WDM）越来越兴趣 - 冷凝物和等离子体之间边界上的异国情调。由于量子的同时重要性和相关效应的重要性，WDM在理论上是复杂的。 \ textit {ab intio}路径积分蒙特卡洛（PIMC）模拟已经扮演关键角色，最近获得了热力学数量的广泛结果。 Dornheim \ textit {et al。} [Phys。莱特牧师。 \ textbf {121}，255001（2018）]。这是基于动态局部场校正的准确重建。在这里，我们将此概念扩展到其他动力学数量的温暖致密电子气体，包括动态敏感性，介电函数和电导率。
There is growing interest in warm dense matter (WDM) -- an exotic state on the border between condensed matter and plasmas. Due to the simultaneous importance of quantum and correlation effects WDM is complicated to treat theoretically. A key role has been played by \textit{ab initio} path integral Monte Carlo (PIMC) simulations, and recently extensive results for thermodynamic quantities have been obtained. The first extension of PIMC simulations to the dynamic structure factor of the uniform electron gas were reported by Dornheim \textit{et al.} [Phys. Rev. Lett. \textbf{121}, 255001 (2018)]. This was based on an accurate reconstruction of the dynamic local field correction. Here we extend this concept to other dynamical quantities of the warm dense electron gas including the dynamic susceptibility, the dielectric function and the conductivity.
