- 論文の詳細を見る
A simple one-dimensional crystal model was proposed in order to study the incommensurate phase formation and its properties were numerically analyzed. In this model each particle(molecule) of the crystal has two degrees of freedom so that a longitudinal sound wave propa-gation is possible. In the case of small displacements and incompressible rnolecules the modelhas the Hamiltonian identical to that for a linear chain with a local fourth order anharmonicpotential and the harmonic nearest- and next-nearest-neighbor interactions. Particular emphasishas been placed on the analysis of the incommensurate phases caused by the soft modes withshort wavelength which has not been studied in most of the previous investigations.
