Standing Wave Localized Squares in Pattern-Forming Nonequilibrium Systems

— We show that stable standing wave localized solutions of square symmetry are possible for a quintic Swift-Hohenberg type equation with complex coefficients. We point out that these localized solutions, which are surrounded by a pattern-free state exist for a range of values for the external stress parameter subcritically. We discuss similarities to recent experimental observations of standing...

Nonlinear pattern and wave-number selection in convecting binary mixtures.

Considerable efforts have recently been made to understand and identify various spatio-temporal transitions from an unstable state to a coherently oscillating or chaotic state in numerous hydrodynamic flows. Oscillatory convection in binary mixtures as well as a variety of open-flow systems show a transition to spatially developing traveling waves (TW). For these systems a generalized Ginzburg-...

Minimum-action paths for wave-number selection in nonequilibrium systems.

The problem of wave-number selections in nonequilibrium pattern-forming systems in the presence of noise is investigated. The minimum-action method is proposed to study the noise-induced transitions between the different spatiotemporal states by generalizing the traditional theory previously applied in low-dimensional dynamical systems. The scheme is shown as an example in the stabilized Kuramo...

Localized states in bistable pattern-forming systems.

We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously generated by the system itself. We show that the phenomenon is generic and requires only the coexistence of two spatially periodic states. At the onset of the spatial bifurc...

Pattern Selection in Programmable Systems

The increase in complexity of integrated circuits results in the need to develop hardware platforms shared among a set of applications in the same domain. Today’s general purpose processors cannot satisfy the future aggressive timing and power constraints for a specific application. On the other hand, conventional ASIC design methodologies are costly and require a long time-to-market for today’...
