Spinodal decomposition : An alternate mechanism of phase conversion
نویسنده
چکیده
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.

Formation of Poly(vinylidene fluoride) Nanofibers Part II: the elaboration of incompatibility in the electrospinning of its solutions
Poly(vinylidene fluoride) (PVDF) fibers with two molecular weights were prepared via electrospinning process. In this process, the concentration of spinning depended drastically on the gelation process. Also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (SENA). Proof of this incompatibility was explained by the properties of PVDF a...
متن کاملOn the nucleation of hadronic domains in the quark-hadron transition
We present numerical results on bubble profiles, nucleation rates and time evolution for a weakly first-order quark-hadron phase transition in different expansion scenarios. We confirm the standard picture of a cosmological first-order phase transition, in which the phase transition is entirely dominated by nucleation. We also show that, even for expansion rates much lower than those expected i...

متن کاملMonte Carlo Simulations for Spinodal Decomposition
This paper addresses the phenomenon of spinodal decomposition for the CahnHilliard equation. Namely, we are interested in why most solutions to the CahnHilliard equation which start near a homogeneous equilibrium u0 in the spinodal interval exhibit phase separation with a characteristic wavelength when exiting a ball of radius R. There are two mathematical explanations for spinodal decompositio...
متن کاملPhase Conversion after a Chiral Transition: Effects from Inhomogeneities and Finite Size∗
We discuss the kinetics of phase conversion, through the nucleation of bubbles and spinodal decomposition, after a chiral transition within an effective field theory approach to low-energy QCD. We study possible effects resulting from the finite size of the expanding system for both the initial and the late-stage growth of domains, as well as those effects due to inhomogeneities in the chiral f...
