Wavefront propagation in a bistable dual-delayed-feedback oscillator: Analogy to networks with nonlocal interactions

Year: 2026

Type: article

Abstract: In the present research, a bistable delayed-feedback oscillator with two delayed-feedback loops is shown to replicate a network of bistable nodes with nonlocal coupling. It is demonstrated that certain aspects of the nonlocal interaction impact on wavefront propagation identified in networks of bistable elements are entirely reproduced in the dynamics of a single oscillator with two delays. In particular, adding the second delayed-feedback loop allows speeding up both deterministic and stochastic wavefront propagation, achieving the stabilization of propagating fronts at lower noise intensity and preventing fronts from noise-induced destruction occurring in the presence of single-delayed-feedback. All the revealed effects are studied in numerical simulations and confirmed in physical experiments, showing an excellent correspondence.
