Summary
We study topological solitons (transition waves) in multistable magnetoelastic lattice. The tunable lattice consists of uniformly magnetized spheres connected by linear springs subjected to a tristable onsite potential. The asymmetry in the potential gives rise to waveforms of three possible transitions even in presence of damping. We then analyze the collision of two similar topological solitons that nucleate a new phase and transform the lattice to a new configuration. Moreover, when two dissimilar topological solitons collide, we observe the creation of a stationary domain wall. These results indicate the richness of dynamical phenomena is multistable lattices and could find applications in: distant actuation in soft robotics, energy storage and design of structures with variable stiffness.
