Aperiodic clustered and periodic hexagonal vegetation spot arrays explained by inhomogeneous environments and climate trends in arid ecosystems
D. Pinto-Ramos, M. G. Clerc, A. Makhoute +1
Due to climate change, overgrazing, and deforestation, arid ecosystems are vulnerable to desertification and land degradation. As aridity increases, vegetation cover loses spatial…

Noise-induced nonreciprocal topological dissipative solitons in directionally coupled chains and lattices
David Pinto-Ramos, Karin Alfaro-Bittner, René G. Rojas +1
Nonreciprocal coupling can alter the transport properties of material media, producing striking phenomena such as unidirectional amplification of waves, boundary modes, or self-ass…

Exact expression for the propagating front velocity in nonlinear discrete systems under nonreciprocal coupling
David Pinto-Ramos
Nonlinear waves are a robust phenomenon observed in complex systems ranging from mechanics to ecology. Fronts are fundamental due to their robustness against perturbations and capa…
