Nonequilibrium criticality driven by Kardar-Parisi-Zhang fluctuations in the synchronization of oscillator lattices

R Gutiérrez, R Cuerno - Physical Review Research, 2023 - APS
The synchronization of oscillator ensembles is pervasive throughout nonlinear science, from
classical or quantum mechanics to biology, to human assemblies. Traditionally, the main …

Kardar-Parisi-Zhang fluctuations in the synchronization dynamics of limit-cycle oscillators

R Gutiérrez, R Cuerno - Physical Review Research, 2024 - APS
The time-dependent process whereby one-dimensional systems of self-sustained oscillators
synchronize is shown to display scale invariance in space and time, akin to that found in the …

Faceted patterns and anomalous surface roughening driven by long-range temporally correlated noise

A Alés, JM López - Physical Review E, 2019 - APS
We investigate Kardar-Parisi-Zhang (KPZ) surface growth in the presence of power-law
temporally correlated noise. By means of extensive numerical simulations of models in the …

Kardar-Parisi-Zhang universality class in the synchronization of oscillator lattices with time-dependent noise

R Gutiérrez, R Cuerno - Physical Review E, 2024 - APS
Systems of oscillators subject to time-dependent noise typically achieve synchronization for
long times when their mutual coupling is sufficiently strong. The dynamical process whereby …

Fragility of Kardar-Parisi-Zhang universality class in the presence of temporally correlated noise

E Rodríguez-Fernández, A Alés, J Martín-Álvarez… - Physical Review E, 2024 - APS
We study numerically a family of surface growth models that are known to be in the
universality class of the Kardar-Parisi-Zhang equation when driven by uncorrelated noise …

Finite-size and finite-time scaling for kinetic rough interfaces

R Chhimpa, AC Yadav - Physical Review E, 2024 - APS
We consider discrete models of kinetic rough interfaces that exhibit space-time scale
invariance in height-height correlation. We use the generic scaling theory of Ramasco et …

Variational formulation for the KPZ and related kinetic equations

HS Wio - International Journal of Bifurcation and Chaos, 2009 - World Scientific
We present a variational formulation for the Kardar–Parisi–Zhang (KPZ) equation that leads
to a thermodynamic-like potential for the KPZ as well as for other related kinetic equations …

Complex dynamics during metal dissolution: From intrinsic to faceted anomalous scaling

P Córdoba-Torres, TJ Mesquita, IN Bastos… - Physical review …, 2009 - APS
The kinetic roughening of dissolving polycrystalline pure iron has been studied. A depth
analysis of surface images has shown two consecutive growth regimes characterized by …

Roughening of the anharmonic Larkin model

VH Purrello, JL Iguain, AB Kolton - Physical Review E, 2019 - APS
We study the roughening of d-dimensional directed elastic interfaces subject to quenched
random forces. As in the Larkin model, random forces are considered constant in the …

Universal interface fluctuations in the contact process

BG Barreales, JJ Meléndez, R Cuerno… - Physical Review E, 2023 - APS
We study the interface representation of the contact process at its directed-percolation
critical point, where the scaling properties of the interface can be related to those of the …
