Figure 1

Comparisons of stopping power for mrel = 1000, and mrel = 1 at the coupling strength values, Γ, of 0.1, 1, and 10. Red-solid curve refers to original EPT model; orange-dashed, purple-dash-dotted, and green-dotted curves, respectively introduce the effects of third to fifth orders of FP method to the original EPT framework. MD results are specified with yellow triangles. To further comparison, the percentage difference of each stopping curves to MD results is expressed in the bar graphs for the two relative masses.
