Energy-driven pattern formation

Abstract: Abstract. Many physical systems can be modelled by nonconvex variational problems regularized by higher-order terms. Examples include martensitic phase transformation, micromagnetics, and the Ginzburg-Landau model of nucleation. We are interested in the singular limit, when the coefficient of the higher-order term tends to zero. Our attention is on the internal structure of walls, and the character of microstructure when it forms. We also study the pathways of thermally-activated transitions, modeled via the m… Show more

“…This implies that there will be no mechanism in any energy-gradient dynamics model that could select a preferred slope of the mounds. See the relevant discussions in [8,9,11,12,21]. The chemical potential is defined to be the variational derivative of the energy (1), i.e.,…”

“…The highly-cited article of Seul and Andelman [25] addresses exactly this issue and provides a partial list of relevant physical systems in Table 1. Problem (1.2) is also very close to variational problems arising in the study of magnetic domains and walls (see for example [15], [12] and the references therein).…”
