Domain wall dynamics in soft magnetic materials
Alexei Vazquez, Oscar Sotolongo-Costa
The dynamics of a domain wall in magnetostrictive materials is investigated. The domain wall is modeled by a d-dimensional interface moving in a d+1-dimensional environment. Long-r…
Self-organized criticality in linear interface depinning and sandpile models
Alexei Vazquez, Oscar Sotolongo-Costa
The dynamics of an elastic interface profile h(x,t) under a driving force increasing at rate c, a restored force -epsilon h, and disorder is investigated. Using perturbation theory…
Fractal approach to the beta relaxation in supercooled liquids
Alexei Vazquez, Oscar Sotolongo-Costa
In the present work we present a fractal model for the beta relaxation in supercooled liquids. The macroscopic dynamics is obtained by superposition of relaxation of independent me…
Avalanche dynamics and nonexponential relaxation
Alexei Vazquez, Oscar Sotolongo Costa, Carlos Antoranz
The theory of SOC, and related avalanche dynamics, is proposed as the origin of the ubiquitous nonexponential relaxation observed in complex systems. Introducing some scaling laws…
Dynamic percolation and Slow Relaxation in Glass-like Materials
A. Vazquez, O. Sotolongo-Costa
Glass-like materials are nonequilibrium systems where the relaxation time may exceed reasonable time scales of observations. In the present paper a dynamic percolation model is int…
