Energy minimizers in a periodic phase transition model of light-matter interaction in nematic liquid crystals Open
In this paper we complete the study of global minimizers of a forced, non autonomous, one dimensional, phase transition model, initiated in [8]. Motivated by the recent findings in [9], revealing new configurations of topological structure…

Nonreciprocal coupling triggers pinning-depinning transitions of wavefronts in bistable systems chains Open
Coupled discrete systems with reciprocal and nonreciprocal couplings exhibit unexpected and counterintuitive phenomena compared to continuous systems. We investigate the pinning-depinning transition induced by nonreciprocal coupling in non…

Nonlinear wave propagation in a bistable optical chain with nonreciprocal coupling Open
The propagation of nonlinear waves, such as fires, weather fronts, and disease spread, has drawn attention since the dawn of time. A well-known example of nonlinear wave–fronts–in our daily lives is the domino waves, which propagate equall…

Nonreciprocal feedback induces migrating oblique and horizontal banded vegetation patterns in hyperarid landscapes Open
In hyperarid environments, vegetation is highly fragmented, with plant populations exhibiting non-random biphasic structures where regions of high biomass density are separated by bare soil. In the Atacama Desert of northern Chile, rainfal…

Traveling spiral wave chimeras in coupled oscillator systems: emergence, dynamics, and transitions Open
Systems of coupled nonlinear oscillators often exhibit states of partial synchrony in which some of the oscillators oscillate coherently while the rest remain incoherent. If such a state emerges spontaneously, in other words, if it cannot …

Topological defects law for migrating banded vegetation patterns in arid climates Open
Self-organization and pattern formation are ubiquitous processes in nature. We study the properties of migrating banded vegetation patterns in arid landscapes, usually presenting dislocation topological defects. Vegetation patterns with di…
