Computer modelling studies of solitons in layered crystals
This paper describes how using a combination of computer modelling techniques, particle track measurements and mathematical analysis, it is possible to show the conditions needed for soliton propagation in the monatomic potassium planes of the layer structured mineral muscovite. Energy minimisation procedures were used to study the changes in energy and interatomic forces as potassium ions were displaced from their equilibrium positions. For displacements along the b crystallographic direction the lateral forces acting on displaced potassium atoms are negligible. The force acting in the direction of displacement is non-linear as a function of displacement. Both of these conditions are consistent with the propagation of solitons in a lattice.
