Topology-driven nonlinear switching in Mobius discrete arrays

Munoz, Francisco J.; Turitsyn, S; Kivshar, Yuri; Molina, Mario I


We examine the switching dynamics of discrete solitons propagating along two coupled discrete arrays which are twisted to form a Möbius strip. We analyze the potential of the topological switches by comparing the differences between the Möbius strip and untwisted discrete arrays. We employ the Ablowitz-Ladik (AL) model and reveal a nontrivial Berry phase associated with the monopole spectra in parameter space. We study the dynamical evolution of the AL soliton launched into one of the chains...[Show more]
