The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

We use an explicitly isochoric two-temperature theory where the ion temperature is not assumed to be equal to the electron temperature, to analyze recent X-ray laser scattering data for Aluminum in the ultra-fast-matter (UFM) regime up to 6 eV, obtained at the Standford Linac Coherent Light Source (LCLS). The observed surprisingly low conductivities are explained by including strong electron-ion scattering effects using the phase shifts calculated via the density-functional neutral-pseudo-atom model (NPA). The applicability of the Mermin model to UFM is questioned. The static and dynamic conductivity, complex collision frequency and the plasmon line-shape are evaluated within a Born approximation and without the use of the Mermin response. This approach, where all needed quantities are obtained from the NPA model, provides good agreement with the reported experimental results.

Original abstract

We use an explicitly isochoric two-temperature theory where the ion temperature is not assumed to be equal to the electron temperature, to analyze recent X-ray laser scattering data for Aluminum in the ultra-fast-matter (UFM) regime up to 6 eV, obtained at the Standford Linac Coherent Light Source (LCLS). The observed surprisingly low conductivities are explained by including strong electron-ion scattering effects using the phase shifts calculated via the density-functional neutral-pseudo-atom model (NPA). The applicability of the Mermin model to UFM is questioned. The static and dynamic conductivity, complex collision frequency and the plasmon line-shape are evaluated within a Born approximation and without the use of the Mermin response. This approach, where all needed quantities are obtained from the NPA model, provides good agreement with the reported experimental results.
