Thermophysical properties of helium using molecular dynamics simulations

The equation of state, melting line and metallization of helium have been studied by using quantum and classical molecular dynamics simulations. The melting line has been obtained by analyzing the radial distribution function and the diffusion parameter which is close to the experimental values. Equations of state when the temperature is less than 4.5 eV and the density is between 0.3 g/cm3 and 5.0 g/cm3 are also studied. Finally, it is found that the temperature can reduce the metallization density and metallization pressure of helium.
