TL;DR

This paper introduces a quantum equation-of-state model for hot dense matter under shock compression, accurately predicting maximum compression and providing analytical estimates that align well with the model.

Contribution

The paper presents a novel quantum equation-of-state model for shock compression, extending predictions beyond fourfold density and estimating maximum compression analytically.

Findings

Good agreement between analytical estimates and the model.

Predictions extend to high-pressure shock Hugoniot curves.

Quantum effects are significant near maximum compression.

Abstract

A quantum equation-of-state model is presented and applied to the calculation of high-pressure shock Hugoniot curves beyond the asymptotic fourfold density, close to the maximum compression where quantum effects play a role. An analytical estimate for the maximum attainable compression is proposed. It gives a good agreement with the equation-of-state model.
