Hence, the LJTS potential is truncated at r e n d and shifted by the corresponding energy value V L J ( r e n d ) . The latter is applied to avoid a discontinuity jump of the potential at r e n d . For the LJTS potential, no long-range interactions beyond r e n d are required – neither explicitly nor implicitly. The most frequently used version of the Lennard-Jones truncated & shifted potential is the one with r e n d = 2.5 σ σ . Nevertheless, different r e n d values have been used in the literature. Each LJTS potential with a given truncation radius r e n d has to be considered as a potential and accordingly a substance of its own.
