Frictional phenomena of two-dimensional elastic lattices are studied numerically based on a two-dimensional Frenkel-Kontorova model with impurities. It is shown that impurities can assist the depinning. We also investigate anisotropic ordering and transverse pinning effects of sliding lattices, which are characteristic of the moving Bragg glass state and/or transverse glass state. Peculiar velocity dependence of the transverse pinning is observed in the presence of both periodic and random…

Incommensurate Structures and Nanoscale Friction at Solid Interfaces

In this study, using numerical simulations based on an incommensurate lattice model at the nanoscale, we investigate the lattice structures of pinned surfaces and the lubrication dynamics of surfaces

Application of two dimensional Frenkel-Kontorova model to nanotribology

The dry friction force between two contacting surface layers is studied. The upper layer is arranged on a two-dimensional square lattice and driven by an external driving force. The lower layer is

Nanoscale Effects Of Surfaces And Lubricants On Friction

Nanoscale frictional phenomena at solid–solid surfaces with lubricants are studied numerically using a lattice model which consists of two rigid substrates and a monolayer of lubricant molecules. The

Order in driven vortex lattices in superconducting Nb films with nanostructured pinning potentials

Driven vortex lattices have been studied in a material with strong pinning, such as Nb films. Samples in which natural random pinning coexists with artificial ordered arrays of defects

Nanoscale Properties of Friction and Lubrication at Solid Interfaces with Lubricants

Nanoscale frictional phenomena at a solid interface with a lubricant layer are studied numerically. We use a model which consists of two rigid substrate lattices with surface impurities and a

Dynamical ordering of driven stripe phases in quenched disorder.

It is found that, when the disorder strength exceeds a critical value, an applied dc drive can induce a dynamical stripe ordering transition to a state that is more ordered than the originating undriven, unpinned pattern.

Numerical study of nanoscale lubrication and friction at solid interfaces

This study investigates lubrication and related frictional phenomena on the nanoscale using numerical simulations. Two models of lubrication, a two-layer and a three-layer, are considered, and for
