| Abstract: | Abstract A three-dimensional model for the octagonal phase based on a cut-projection from the eight-dimensional hypercubic lattice is presented here. The phason-phonon coupling which leads the octagonal phase into 45° twinned cubic ones is also studied. Conclusions of this realistic model do not modify the previously stated conclusions from the standard but incomplete two-dimensional treatment. |
