The role of domain walls in energy transfer mechanisms between two connected one-dimensional ferroelectrics

Abstract

A statistical treatment of energy transfer from one ferroelectric chain to another through the mechanism of domain-wall solitons is presented. Two one-dimensional ferroelectric chains are considered which have a junction point enabling energy exchange between the chains. The contribution of domain-wall mechanism in the energy transfer process is compared to the contribution due to the mechanism of linear excitations in the chains.
