Spinodal decomposition: An alternate mechanism of phase conversion

Spinodal decomposition : An alternate mechanism of phase conversion

The scenario of homogeneous nucleation is investigated for a first order quarkhadron phase transition in a rapidly expanding background of quark gluon plasma. It is found that significant supercooling is possible before hadronization begins. This study also suggests that spinodal decomposition competes with nucleation and may provide an alternative mechanism for phase conversion.

Spinodal Decomposition and the Deconfining Phase Transition

Lattice gauge theory investigations of the deconfining phase transitions have mainly been limited to equilibrium studies (an exception is the work by Miller and Ogilvie [1]). The equilibrium transition with two massless quarks is likely second order and it becomes a crossover with two light quarks (and the heavier strange quark) [2]. In nature the finite temperature phase transition is governed...

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...

Quantum spinodal decomposition.

We study the process of spinodal decomposition in a scalar quantum field theory that is quenched from an equilibrium disordered initial state at Ti > Tf to a final state at Tf ≈ 0. The process of formation and growth of correlated domains is studied in a Hartree approximation. We find an approximate scaling law for the size of the domains ξD(t) ≈ √ tξ0 at long times for weakly coupled theories,...
