Temperature relaxation in hot dense hydrogen.
Temperature equilibration of hydrogen is studied for conditions relevant to inertial confinement fusion. New molecular-dynamics simulations and results from quantum many-body theory are compared with Landau-Spitzer predictions for temperatures T with 50<T<4000 eV and densities with Wigner-Seitz radii rs=1.0 and 0.5. The relaxation is slower than the Landau-Spitzer result, even for T in the kilo-electron-volt range, but converge to agreement in the high-T limit.
