Structural relaxation and conductivity relaxation in glassy ionics

Aging of the secondary relaxation to probe structural relaxation in the glassy state.

The importance of glass formation and the glass transition is linked to their universality, embracing many classes of materials: metallic, inorganic, and organic. There is no agreement on what drives this phenomenon; moreover, experiments are challenging due to the nonequilibrium nature of the glassy state. We present a new approach that provides information about the very slow structural relax...

Structural relaxation of glassy selenium under γ irradiation

2014 The effect of 03B3-rays on the structural relaxation of glassy selenium near the glass transition has been studied by dilatometry. We show that under irradiation the evolution time scale shifts about one decade. J. Physique LETTRES 42 (1981) L-501-L-502 . Classification Physics Abstracts 61.40D 64.70E 61.80E 15 NOVEMBRE 1981,

Stimulated and spontaneous relaxation in glassy systems

Recent numerical simulations of a disordered system [5] have shown the existence of two different relaxational processes (called stimulated and spontaneous) characterizing the relaxation observed in structural glasses. The existence of these two processes has been claimed to be at the roots of the intermittency phenomenon observed in recent experiments. Here we consider a generic system put in ...

Ubiquitous "glassy" relaxation in catalytic reaction networks.

Study of reversible catalytic reaction networks is important not only as an issue for chemical thermodynamics but also for protocells. From extensive numerical simulations and theoretical analysis, slow relaxation dynamics to sustain nonequlibrium states are commonly observed. These dynamics show two types of salient behaviors that are reminiscent of glassy behavior: slow relaxation along with ...
