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.
