Quantum Spinodal Decomposition

Abstract

We study the process of spinodal decomposition in a scalar quantum field theory that is quenched from an equilibrium disordered initial state at $T_i>T_f$ to a final state at $T_f\approx 0$. 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 ${\xi }_D(t)\approx \sqrt{t{\xi }_0}$ at long times for weakly coupled theories, with ${\xi }_0$ the zero temperature correlation length.
