Growing timescales and lengthscales characterizing vibrations of amorphous solids.
Low-temperature properties of crystalline solids can be understood using harmonic perturbations around a perfect lattice, as in Debye's theory. Low-temperature properties of amorphous solids, however, strongly depart from such descriptions, displaying enhanced transport, activated slow dynamics across energy barriers, excess vibrational modes with respect to Debye's theory (i.e., a boson peak),...
متن کاملPharmaceutical Solids — The Amorphous Phase
“Pharmaceutical Solids” discusses scientific principles associated with pharmaceutical solids useful to practitioners in validation and compliance. We intend this column to help the understanding of principles associated with pharmaceutical solids and to be a useful resource for daily work applications. Enhanced process understanding is an important objective of the quality-by-design initiative...
متن کاملHidden structure in amorphous solids
Review copy ± not for distribution (pss-logo will be inserted here by the publisher) pss-‐Header will be provided by the publisher 1 Introduction The continuous random network (CRN) has become the accepted model for homogeneously disordered materials, and for good reason: such atomistic models reproduce the experimentally observed properties of the materials, including some of the finer detail...
متن کاملThe plastic response of magnetoelastic amorphous solids
We address the cross-effects between mechanical strains and magnetic fields on the plastic response of magnetoelastic amorphous solids. It is well known that plasticity in nonmagnetic amorphous solids under external strain γ is dominated by the codimension-1 saddle-node bifurcation in which an eigenvalue of the Hessian matrix vanishes at γP like √ γP − γ. This squareroot singularity determines ...
متن کاملBreakdown of continuum elasticity in amorphous solids.
We show numerically that the response of simple amorphous solids (elastic networks and particle packings) to a local force dipole is characterized by a lengthscale lc that diverges as unjamming is approached as lc ∼ (z - 2d)(-1/2), where z ≥ 2d is the mean coordination, and d is the spatial dimension, at odds with previous numerical claims. We also show how the magnitude of the lengthscale lc i...
