Fig. 4: Comparison of potential energy and displacement dynamics using various interatomic potentials.

a Short-range potential energy per atom for a tungsten dimer, calculated using various interatomic potentials and compared with DFT results. The M-S_s potential exhibits a clear deviation from the others. b Time progression of the total squared displacement (Å2) in representative collision cascades triggered by 10 keV PKA.
