Roughening of active nonlinear interfaces with broken tilt symmetry
Ailén M. Cámara, Alejandro B. Kolton, José Luis IguaÃn
We study the roughening of an interface with nonlinear elasticity driven by temporally correlated noise, which breaks statistical tilt symmetry. Using scaling arguments and a self-…
Geometric flow of planar domain-wall loops
Pablo Domenichini, German Salazar, Alejandro B. Kolton
We investigate the geometric evolution of elastic domain-wall loops in two dimensions. Assuming an instantaneous, isotropic, and homogeneous arc-velocity response of the domain wal…
Data-Driven Modelling to predict forest fire spread in the Patagonian region in Argentina
Lucas Becerra, Monica Malen Denham, Alejandro B. Kolton +1
Wildfires are among the most severe disturbances affecting forest ecosystems, with over 50,000 hectares burned in Patagonia, Argentina, during 2025 alone. This study implements a R…
Activation and Avalanche Length Scales in the Finite-Temperature Creep of an Elastic Interface
Giovanni Russo, Ezequiel E. Ferrero, Alejandro B. Kolton +2
We investigate the creep dynamics of a driven elastic line at finite temperature, well below the depinning threshold. We show that creep is governed by two distinct length scales.…
Deterministic roughening in the dc-driven precessional regime of domain walls
E. F. Pusiol, V. Lecomte, S. Bustingorry +1
We numerically study the dynamics of extended domain walls in homogeneous ferromagnets driven by a uniform magnetic field at zero temperature. Using both micromagnetic Landau-Lifsh…
Hyperuniform patterns nucleated at low temperatures: Insight from vortex matter imaged in unprecedentedly large fields-of-view
Alexey Cruz-GarcÃa, JoaquÃn Puig, Sergii Pylypenko +4
Hyperuniform patterns present enhanced physical properties that make them the new generation of cutting-edge technological devices. Synthesizing devices with tens of thousands of c…
