Ab-Initio Stopping power in the warm dense matter regime by Orbital-free Time Dependent DFT


Image shows graphs depicting experimental and simulated alpha particle projectile.

Left-Top: Experimental & simulated alpha particle projectile velocity distributions before & after stopping by warm dense Beryllium. Right-Top: TD-OF-DFT calculated deuteron stopping 8 power of warm & hot dense Deuterium, up to 1 million Kelvin. Bottom: TD-OF-DFT simulated 6 electron density difference, showing the full simulation window (1029 atoms).

A novel orbital-free density functional theory approach provides ab-initio simulations of nonadiabatic stopping power in the previously inaccessible hot and warm dense matter environment.
