Phase transformations in highly excited clusters
In this communication we analyze the behavior of excited drops that undergo fragmentation. We focus our attention on two scenarios: in the first one the system is free to expand, while in the second one it is confined inside a spherical volume. It is shown that the caloric curve of free expanding sy...

| Sumario: | In this communication we analyze the behavior of excited drops that undergo fragmentation. We focus our attention on two scenarios: in the first one the system is free to expand, while in the second one it is confined inside a spherical volume. It is shown that the caloric curve of free expanding systems does not display a vapor branch. In the case of constrained ones, they behave as undergoing a first order phase transition at low densities while as a second order one at high densities. The transition from liquid-like to vapor-like behavior is signaled both by the caloric curves and thermal response functions. |
