<i>Ab initio</i> calculated dynamic structural factors and optical properties of beryllium along the Hugoniot

Beryllium is an ablator material used in inertial-confinement fusion and hypervelocity impact studies. The thermoelastic properties, structural factors, optical properties of beryllium are important these In this paper, the static ion–ion dynamic adiabatic velocity, along Hugoniot were calculated by ab initio simulations. factors show that atoms randomly distributed. extracted dispersion relation for collective excitation via scattering function. By collecting peak position sound velocity derived definition. Using equation state, have been derived. two methods verified to be equivalent.
