Spatial Correlations and Higher-Order Gradient Terms in a Continuum Description of Dislocation Dynamics
The problem of the collective behavior of straight parallel edge dislocations is investigated. Starting from the equation of motion of individual dislocations a continuum description is derived. ItExpand

Dislocation Avalanches, Strain Bursts, and the Problem of Plastic Forming at the Micrometer Scale
Under stress, many crystalline materials exhibit irreversible plastic deformation caused by the motion of lattice dislocations. In plastically deformed microcrystals, internal dislocation avalanchesExpand

Interactions between polymers and carbon nanotubes: a molecular dynamics study.
We used force-field-based molecular dynamics to study the interaction between polymers and carbon nanotubes (CNTs). The intermolecular interaction energy between single-walled carbon nanotubes andExpand

Strain bursts in plastically deforming molybdenum micro- and nanopillars
Plastic deformation of micron and sub-micron scale specimens is characterized by intermittent sequences of large strain bursts (dislocation avalanches) which are separated by regions of near-elasticExpand

FRACTAL DISLOCATION PATTERNING DURING PLASTIC DEFORMATION
During the later stages of plastic deformation, strain hardening of face-centered cubic metals goes along with the formation of cellular dislocation patterns appearing on various scales. The paperExpand

Fluctuation phenomena in crystal plasticity—a continuum model
On microscopic and mesoscopic scales, plastic flow of crystals is characterized by large intrinsic fluctuations. Deformation by crystallographic slip occurs in a sequence of intermittent burstsExpand

Continuum dislocation dynamics: Towards a physical theory of crystal plasticity
The plastic deformation of metals is the result of the motion and interaction of dislocations, line defects of the crystalline structure. Continuum models of plasticity, however, remain largelyExpand

Self-affine surface morphology of plastically deformed metals.
We analyze the surface morphology of metals after plastic deformation over a range of scales from 10 nm to 2 mm using atomic force microscopy and scanning white-light interferometry. We demonstrateExpand

A compact dual atom interferometer gyroscope based on laser-cooled rubidium
AbstractWe present a compact and transportable inertial sensor for precision sensing of rotations and accelerations. The sensor consists of a dual atom interferometer operated with laser-cooled 87Rb.Expand
