Serration and noise behaviors in plastically deforming solids are related to avalanches of
deformation processes. In the stress-strain curves, the serration characteristics are visible as …

We revisit the concept of marginal stability in glasses and determine its range of applicability
in the context of an avalanche-type response to slow external driving. We argue that there is …

Hysteresis loops are often seen in experiments at first-order phase transformations, when
the system goes out of equilibrium. They may have a macroscopic jump (roughly as in the …

We investigate the scaling properties of the Barkhausen effect by recording the noise in
several soft ferromagnetic materials: polycrystals with different grain sizes and amorphous …

We present numerical simulations of avalanches and critical phenomena associated with
hysteresis loops, modeled using the zero-temperature random-field Ising model. We study …

We review key experimental and theoretical results on the Barkhausen effect, focusing on
the statistical analysis of the noise. We discuss the experimental methods and the material …

We show that the first order magneto-structural phase transitions observed in various
classes of magnetic solids are often accompanied by useful multi-functional properties …

Publisher Summary This chapter discusses vibrational properties of shape-memory alloys.
The crystal structure of a given material depends on its energy and also its entropy, which …

We have studied the effect of disorder on the martensitic transformation (MT), especially on
the hysteretic behavior of Ti-Nb-O alloy. This system allows arbitrary tuning of the amount of …

This is a review article of our work on hysteresis, avalanches, and criticality. We provide an
extensive introduction to scaling and renormalization--group ideas, and discuss analytical …
