Abstract: We present a systematic study of the thermodynamics of two and three-dimensional generalized Lennard–Jones (LJ) systems focusing on the relationship between the range of the potential, the system density and its dimension. We found that the existence of negative specific heats depends on these three factors and not only on the potential range and the density of the system as stated in recent contributions.
