Transitions between Phases with Equal Wave Numbers in a Double Ising Spin Model. Application to Betaine Calcium Chloride Dihydrate
Boris Neubert, Michel Pleimling, Rolf Siems
A Double Ising Spin model for uniaxially structurally modulated materials exhibits as a special feature phase transitions between phases with equal wave numbers but different pseud…
Low temperature phase diagram and critical behaviour of the four-state chiral clock model
M. Pleimling, B. Neubert, R. Siems
The low temperature behaviour of the four-state chiral clock () model is reexamined using a systematic low temperature series expansion of the free energy. Previously obtaine…
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…
