Experiments and simulations on hot expanded boron.
We measured the thermodynamical and transport properties of boron in the warm dense matter regime ( 15000 K<T<25000 K and rho=0.094 g/cm3). Experimental data are compared with quantum molecular dynamics (QMD) simulations. We find a very good agreement between data and calculations, which permits us to transform experimental energies into temperatures, and allows us to compare conductivities with an average atom model coupled with a Kubo-Greenwood calculations. Contact is made between computationally intensive QMD simulation codes and fast average atom models.
