Quantum Spinodal Decomposition
Daniel Boyanovsky
Abstract
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) ≈ t ξ0 at long times for weakly coupled theories, with ξ0 the zero temperature correlation length.
