Unidirectional Transition Waves in Bistable Lattices.
We present a model system for strongly nonlinear transition waves generated in a periodic lattice of bistable members connected by magnetic links. The asymmetry of the on-site energy wells created by the bistable members produces a mechanical diode that supports only unidirectional transition wave propagation with constant wave velocity. We theoretically justify the cause of the unidirectionali...

where L is the lattice parameter and p < −1. We can therefore deduce the following relations: 1. The mass density should be a constant: m/L = constant ⇒ m = O(L). 2. The energy density of the nonlinear spring should be constant: − A p+1 (un+1 − un + L) p+1 /L = − A p+1 (L + L) p+1 /L = constant ⇒ A = O(L−p) where ∼ O(1). 3. The energy density of the bistable function should be constant: βφ(un)/...
متن کاملRotary bistable and Parametrically Excited Vibration Energy Harvesting
Parametric resonance is a type of nonlinear vibration phenomenon [1], [2] induced from the periodic modulation of at least one of the system parameters and has the potential to exhibit interesting higher order nonlinear behaviour [3]. Parametrically excited vibration energy harvesters have been previously shown to enhance both the power amplitude [4] and the frequency bandwidth [5] when compare...
متن کاملLoops of Energy Bands for Bloch Waves in Optical Lattices
We consider stationary Bloch waves in a Bose–Einstein condensate placed in a periodic potential for varying strengths of inter-atomic interactions. Bifurcations of the stationary states are known to occur in this context. These bifurcations generate loops in the energy bands of the Bloch waves near the ends and the center of the Brillouin zone. Using themethod of Lyapunov–Schmidt reductions, we...
متن کاملBistable transition fronts in R
This paper is chiefly concerned with qualitative properties of some reaction-diffusion fronts. The recently defined notions of transition fronts generalize the standard notions of traveling fronts. In this paper, we show the existence and the uniqueness of the global mean speed of bistable transition fronts in RN . This speed is proved to be independent of the shape of the level sets of the fro...
