  • Existing methods for temperature estimation of warm dense matter rely on model calculations. Here the authors report a method to extract the temperature of complex materials that is previously only inferred by using model calculations.

  • Path-integral Monte Carlo (PIMC) techniques are used to simulate thermodynamic properties of warm dense matter but currently suffer from uncontrolled approximations and exponentially scaling computational costs. Here, the authors provide a way to overcome these issues, developing PIMC simulations of warm dense beryllium in agreement with x-ray Thomson scattering.

  • Relativistic laser-solid interactions are simulated via particle-in-cell (PIC) approaches, while subrelativistic regimes rely on radiation-hydrodynamics formulations. To validate the methods at the transition from relativistic to subrelativistic laser intensities, the authors propose a testbed to experimentally benchmark PIC simulations.

  • Accurate understanding of the dynamics of correlated quantum many-body systems is of interest in many fields. Here the authors explain the exchange–correlation induced red-shift and incipient roton feature of the dynamic structure factor of the warm dense electron gas in terms of electronic pair alignment model.
