1 2 D ec 2 00 3 Caloric Curves in two and three-dimensional Lennard-Jones-like systems including Long-range forces

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… CONTINUE READING
