Compact-like kink in a real electrical reaction–diffusion chain

We demonstrate experimentally the compact-like kinks existence in a real electrical reaction–diffusion chain. Our measures show that such entities are strictly localized and consequently present a finite spatial extent. We show equally that the kink velocity is threshold-dependent. A theoretical qua...

Description
Summary:We demonstrate experimentally the compact-like kinks existence in a real electrical reaction–diffusion chain. Our measures show that such entities are strictly localized and consequently present a finite spatial extent. We show equally that the kink velocity is threshold-dependent. A theoretical quantification of the critical coupling under which propagation fails is also achieved and reveals that nonlinear coupling leads to a propagation failure reduction.
