| Abstract: | The properties of discommensurations in modulated phases of the ANNNI-(Axial Next Nearest Neighbour Interaction) model are described. A method is presented for deriving wall profiles, free energies, and interaction energies from a fixed point expansion of the 4d mapping representing the MFA equilibrium equations. Implications for the characteristics of phase diagrams and transitions are discussed. |
