摘要
Quantum molecular dynamic simulations have been employed to study the equation of state(EOS)of fluid helium under shock compressions.The principal Hugoniot is determined from EOS,where corrections from atomic ionization are added onto the calculated data.Our simulation results indicate that principal Hugoniot shows good agreementwith gas gun and laser driven experiments,andmaximum compression ratio of 5.16 is reached at 106 GPa.
