CONFINED STATES IN PHASE DYNAMICS - THE INFLUENCE OF BOUNDARY-CONDITIONS AND TRANSIENT-BEHAVIOR

Confined states in phase dynamicsthe coexistence of states with different wavelengthsare further studied. In particular, a stable and accurate numerical code is developed to study the dynamic equation of motion for two sets of boundary conditionsa pinned phase and an unpinned phase. With a pinned phase, stable confined states are found to exist for a wide range of parameter values. With an unpinned phase, the localized states are at best neutrally stable. Also, analytic solutions are found for the stationary confined states. © 1990 The American Physical Society.
