Models for the description of uniaxially modulated materials
Boris Neubert, Michel Pleimling, Rolf Siems
Models which allow an explicit application to structurally modulated substances are reviewed within the frame of a symmetry-based approach starting from discrete lattice theory. Fo…

Derivation of symmetry-based pseudo spin models for modulated materials
Boris Neubert, Michel Pleimling, Rolf Siems
A general concept for the derivation of symmetry-based pseudo spin Hamiltonians is described. It systematically bridges the gap between the atomistic basis and various pseudo spin…
