Non-Trivial Algebraic Decay in a Soluble Model of Coarsening
Non-Trivial Algebraic Decay in a Soluble Model of Coarsening
A non-trivial exponent β characterising non-equilibrium coarsening processes is calculated in a soluble model. For a spin model, the exponent describes how the fraction p0 of spins which have never flipped (or, equivalently, the fraction of space which has never been traversed by a domain wall) depends on the characteristic …
