Enhancing energy harvesting by coupling monostable oscillators
J. I. Pena Rossello, H. S. Wio, R. R. Deza +1
The performance of a ring of linearly coupled, monostable nonlinear oscillators is optimized towards its goal of acting as energy harvester---through piezoelectric transduction---o…
KPZ dynamics from a variational perspective: potential landscape, time behavior, and other issues
Horacio S Wio, Miguel A Rodríguez, R Gallego +2
The deterministic KPZ equation has been recently formulated as a gradient flow, in a nonequilibrium potential (NEP) \[Φ[h(\mathbf{x},t)]=\int\mathrm{d}\mathbf{x}\left[\fracν{2}(\na…
Piezoelectric energy harvesting from colored fat-tailed fluctuations: An electronic analogy
J. I. Peña Rosselló, R. R. Deza, J. I. Deza +1
Aiming to optimize piezoelectric energy harvesting from strongly colored fat-tailed fluctuations, we have recently studied the performance of a monostable inertial device under a n…
Invited review: KPZ. Recent developments via a variational formulation
Horacio S. Wio, Roberto R. Deza, Carlos Escudero +1
Recently, a variational approach has been introduced for the paradigmatic Kardar--Parisi--Zhang (KPZ) equation. Here we review that approach, together with the functional Taylor ex…
Discretization-related issues in the KPZ equation: Consistency, Galilean-invariance violation, and fluctuation--dissipation relation
H. S. Wio, J. A. Revelli, R. R. Deza +2
In order to perform numerical simulations of the KPZ equation, in any dimensionality, a spatial discretization scheme must be prescribed. The known fact that the KPZ equation can b…
Highly synchronized noise-driven oscillatory behavior of a FitzHugh-Nagumo ring with phase-repulsive coupling
Gonzalo G. Izús, Roberto R. Deza, Alejandro D. Sánchez
We investigate a ring of FitzHugh--Nagumo elements coupled in \emph{phase-repulsive} fashion and submitted to a (subthreshold) common oscillatory signal and independent Gaussia…
