+%The cut-off function of the short range potential limits the interaction to nearest neighbors, which results in overestimated and unphysical high forces between neighbored atoms.
+The cut-off function of the short range potential limits the interaction to nearest neighbors.
+Since the total binding energy is, thus, accommodated within this short distance, which according to the universal energy relation would usually correspond to a much larger distance, unphysical high forces between two neighbored atoms arise.
+While cohesive and formational energies are often well described, these effects increase for non-equilibrium structures and dynamics.
