Increasing power-law range in avalanche amplitude and energy distributions
Víctor Navas-Portella, Isabel Serra, Álvaro Corral +1
Power-law type probability density functions spanning several orders of magnitude are found for different avalanche properties. We propose a methodology to overcome empirical const…
Influence of the aspect ratio and boundary conditions on universal finite size scaling functions in the athermal metastable 2d Random Field Ising Model
Víctor Navas-Portella, Eduard Vives
This work studies universal finite size scaling functions for the number of 1d spanning avalanches in a two-dimensional disordered system with boundary conditions of different natu…
Analysis of power-law exponents by maximum-likelihood maps
Jordi Baró, Eduard Vives
Maximum-likelihood exponent maps have been studied as a technique to increase the understanding and improve the fit of power-law exponents to experimental and numerical simulation…
Uncertainty Relations in Statistical Mechanics: a numerical study in small lattice systems
Genís Torrents, Eduard Vives, Antoni Planes
We have analyzed the validity of uncertainty relations between the fluctuations of thermodynamically conjugated extensive and intensive variables within the field of statistical me…
Statistics of Microstructure Formation in Martensitic Transitions Studied by a Random-Field Potts Model with Dipolar-like Interactions
B. Cerruti, E. Vives
We have developed a simple model for the study of a cubic to tetragonal martensitic transition, under athermal conditions, in systems with a certain amount of disorder. We have per…
Random Field Potts model with dipolar-like interactions: hysteresis, avalanches and microstructure
Benedetta Cerruti, Eduard Vives
A model for the study of hysteresis and avalanches in a first-order phase transition from a single variant phase to a multivariant phase is presented. The model is based on a modif…
