Spinodal decomposition of expanding nuclear matter and multifragmentation

Density fluctuations of expanding nuclear matter are studied within a mean–field model in which fluctuations are generated by an external stochastic field. The time evolution of the system is studied in a kinetic–theory approach. In this model fluctuations develop about a mean one–body phase–space density corresponding to a hydrodynamic motion that describes a slow expansion of the system. A fl...

Fragment Charge Correlations and Spinodal Decomposition in Finite Nuclear Systems

Enhanced production of events with almost equal-sized fragments is experimentally revealed by charge correlations in the multifragmentation of a finite nuclear system selected in Xe central collisions on Sn. The evolution of their weight with the incident energy: 32, 39, 45, 50 AMeV, is measured. Dynamical stochastic mean field simulations performed at 32 AMeV, in which spinodal instabilities a...

Spinodal decomposition in microemulsions

Parallel Spinodal Decomposition

Spinodal decomposition encompasses the ordering dynamics of thermodynamically unstable phases. An example of spinodal decomposition is the separation of the metals in a binary alloy. Because physicists have been unable to develop a fully coherent, consistent , and calculable theory on spinodal decomposition, computational studies have served as valuable sources of information. However, since th...
