Coarsening in inhomogeneous systems
Federico Corberi
TL;DR
This paper reviews coarsening phenomena in inhomogeneous systems, focusing on ferromagnetic systems with quenched disorder, and discusses growth laws and scaling properties of ordered domains.
Contribution
It provides a concise overview of how quenched inhomogeneities affect coarsening dynamics and scaling in ferromagnetic systems.
Findings
Growth laws depend on disorder type
Scaling properties are modified by inhomogeneities
Current understanding emphasizes non-conserved order parameters
Abstract
This Article is a brief review of coarsening phenomena occurring in systems where quenched features - such as random field, varying coupling constants or lattice vacancies - spoil homogeneity. We discuss the current understanding of the problem in ferromagnetic systems with a non-conserved scalar order parameter by focusing primarily on the form of the growth-law of the ordered domains and on the scaling properties.
