Microscopic interplay of temperature and disorder of a one-dimensional elastic interface
Nirvana Caballero, Thierry Giamarchi, Vivien Lecomte +1
Elastic interfaces display scale-invariant geometrical fluctuations at sufficiently large lengthscales. Their asymptotic static roughness then follows a power-law behavior, whose a…
A numerical study of the statistics of roughness parameters for fluctuating interfaces
Sebastian Bustingorry, Jill Guyonnet, Patrycja Paruch +1
Self-affine rough interfaces are ubiquitous in experimental systems, and display characteristic scaling properties as a signature of the nature of disorder in their supporting medi…
Field-dependent roughness of moving domain walls in a Pt/Co/Pt magnetic thin film
María José Cortés Burgos, Pamela C. Guruciaga, Daniel Jordán +5
The creep motion of domain walls driven by external fields in magnetic thin films is described by universal features related to the underlying depinning transition. One key paramet…
Mean-field dynamics of infinite-dimensional particle systems: global shear versus random local forcing
Elisabeth Agoritsas
In infinite dimension, many-body systems of pairwise interacting particles provide exact analytical benchmarks for features of amorphous materials, such as the stress-strain curve…
From bulk descriptions to emergent interfaces: connecting the Ginzburg-Landau and elastic line models
Nirvana Caballero, Elisabeth Agoritsas, Vivien Lecomte +1
Controlling interfaces is highly relevant from a technological point of view. However, their rich and complex behavior makes them very difficult to describe theoretically, and henc…
Statistics of roughness for fluctuating interfaces: A survey of different scaling analyses
J. Guyonnet, E. Agoritsas, P. Paruch +1
Ferroic domain walls are known to display the characteristic scaling properties of self-affine rough interfaces. Different methods have been used to extract roughness information i…
Out-of-equilibrium dynamical equations of infinite-dimensional particle systems. II. The anisotropic case under shear strain
Elisabeth Agoritsas, Thibaud Maimbourg, Francesco Zamponi
As an extension of the isotropic setting presented in the companion paper [J. Phys. A 52, 144002 (2019)], we consider the Langevin dynamics of a many-body system of pairwise intera…
Out-of-equilibrium dynamical equations of infinite-dimensional particle systems. I. The isotropic case
Elisabeth Agoritsas, Thibaud Maimbourg, Francesco Zamponi
We consider the Langevin dynamics of a many-body system of interacting particles in dimensions, in a very general setting suitable to model several out-of-equilibrium situation…
Out-of-equilibrium dynamical mean-field equations for the perceptron model
Elisabeth Agoritsas, Giulio Biroli, Pierfrancesco Urbani +1
Perceptrons are the building blocks of many theoretical approaches to a wide range of complex systems, ranging from neural networks and deep learning machines, to constraint satisf…
Static fluctuations of a thick 1D interface in the 1+1 Directed Polymer formulation: numerical study
Elisabeth Agoritsas, Vivien Lecomte, Thierry Giamarchi
We study numerically the geometrical and free-energy fluctuations of a static one-dimensional (1D) interface with a short-range elasticity, submitted to a quenched random-bond Gaus…
Static fluctuations of a thick 1D interface in the 1+1 Directed Polymer formulation
Elisabeth Agoritsas, Vivien Lecomte, Thierry Giamarchi
Experimental realizations of a 1D interface always exhibit a finite microscopic width ; its influence is erased by thermal fluctuations at sufficiently high temperatures, but…
Disordered Elastic Systems and One-Dimensional Interfaces
Elisabeth Agoritsas, Vivien Lecomte, Thierry Giamarchi
We briefly introduce the generic framework of Disordered Elastic Systems (DES), giving a short `recipe' of a DES modeling and presenting the quantities of interest in order to prob…
Temperature-induced crossovers in the static roughness of a one-dimensional interface
Elisabeth Agoritsas, Vivien Lecomte, Thierry Giamarchi
At finite temperature and in presence of disorder, a one-dimensional elastic interface displays different scaling regimes at small and large lengthscales. Using a replica approach…
