Nonequilibrium dynamics in an amorphous solid.
نویسندگان
چکیده
The nonequilibrium dynamics of an amorphous solid is studied with a soft-spin model. We show that the aging behavior in the glassy state follows a modified Kohlrausch-Williams-Watts form similar to that obtained in Lunkenheimer [Phys. Rev. Lett. 95, 055702 (2005)] from analysis of the dielectric loss data. The nature of the fluctuation-dissipation theorem violation is also studied in time as well as correlation windows.

Theory of amorphous ices.
We derive a phase diagram for amorphous solids and liquid supercooled water and explain why the amorphous solids of water exist in several different forms. Application of large-deviation theory allows us to prepare such phases in computer simulations. Along with nonequilibrium transitions between the ergodic liquid and two distinct amorphous solids, we establish coexistence between these two am...
متن کاملMacroscopic yielding in jammed solids is accompanied by a nonequilibrium first-order transition in particle trajectories.
We use computer simulations to analyze the yielding transition during large-amplitude oscillatory shear of a simple model for soft jammed solids. Simultaneous analysis of global mechanical response and particle-scale motion demonstrates that macroscopic yielding, revealed by a smooth crossover in mechanical properties, is accompanied by a sudden change in the particle dynamics, which evolves fr...
متن کاملAmorphous nucleation precursor in highly nonequilibrium fluids.
Dynamical density-functional simulations reveal structural aspects of crystal nucleation in undercooled liquids: The first appearing solid is amorphous, which promotes the nucleation of bcc crystals but suppresses the appearance of the fcc and hcp phases. These findings are associated with features of the effective interaction potential deduced from the amorphous structure.
متن کاملNonequilibrium thermodynamics of driven amorphous materials. I. Internal degrees of freedom and volume deformation.
This is the first of three papers devoted to the nonequilibrium thermodynamics of amorphous materials. Our focus here is on the role of internal degrees of freedom in determining the dynamics of such systems. For illustrative purposes, we study a solid whose internal degrees of freedom are vacancies that govern irreversible volume changes. Using this model, we compare a thermodynamic theory bas...
متن کاملClassical Dynamics Description of Low Energy Cascades in Solids: Atomic Ejection from Amorphous Argon
A classical dynamics calculation of atomic ejection due to a 1 eV kinetic energy impulse to a single atom is made for an amorphous argon solid. Impulses of this magnitude occur following electronic stimulation of the solid. The calculations show that the energized atom produces a collision sequence that results in a recoil spectrum similar to that predicted for binary collisions and to those ca...
