Static displacements and chemical correlations in alloys
Recent experiments in metallic solid solutions have revealed interesting correlations between static pair-displacements and the ordering behavior of these alloys. This paper discusses a simple theoretical model which successfully explains these observations and which provides a natural framework for analyzing experimental measurements of pair-displacements and chemical correlations in solid sol...
متن کاملSpatial correlations of particle displacements in a glass-forming liquid
We de ne a generic correlation function that quanti es the spatial correlation of single-particle displacements in liquids and amorphous systems. We evaluate this function using computer simulations of an equilibrium glass-forming liquid, and show that the displacements of particles are spatially correlated over a range that grows with decreasing temperature as the glass transition is approache...
متن کاملStatic and dynamic displacements of foundations on heterogeneous multilayered soils
An analytical-numerical formulation is presented for dynamic and static analysis of strip foundations on an elastic isotropic medium consisting of heterogeneous layers. Each layer is characterized by an S-wave velocity that increases or decreases linearly with depth, a constant material density, a constant Poisson’s ratio equal to l/4 and a constant linearlyhysteretic critical damping ratio. Th...
متن کاملStatic and dynamic correlations in water at hydrophobic interfaces.
We study the static and dynamic properties of the water-density fluctuations in the interface of large nonpolar solutes. With the help of extensive molecular dynamics simulations of TIP4P water near smooth spherical solutes, we show that for large solutes, the interfacial density profile is broadened by capillary waves. For purely repulsive solutes, the squared width of the interface increases ...
متن کاملGeometrical frustration and static correlations in a simple glass former.
We study the geometrical frustration scenario of glass formation for simple hard-sphere models. We find that the dual picture in terms of defects brings little insight and no theoretical simplification for the understanding of the slowing down of relaxation, because of the strong frustration characterizing these systems. The possibility of a growing static length is furthermore found to be phys...
