The static properties of multi-chain Frenkel–Kontorova model: ground state and static friction
نویسندگان
چکیده
The static properties of the multi-chain Frenkel–Kontorova model are studied numerically. In the case of incommensurate structure, the transition by breaking of analyticity appears in each chain. A new hull function h(x), which also shows the transition by breaking of analyticity, is defined. The static friction (depinning force) depends strongly on the strength of the substrate potential, the number of chains and the strength of the interaction between chains. 2002 Elsevier Science B.V.

Emergent friction in two-dimensional Frenkel-Kontorova models.
Simple models for friction are typically one-dimensional, but real interfaces are two-dimensional. We investigate the effects of the second dimension on static and dynamic friction by using the Frenkel-Kontorova (FK) model. We study the two most straightforward extensions of the FK model to two dimensions and simulate both the static and dynamic properties. We show that the behavior of the stat...
متن کاملFractal spin glass properties of low energy configurations in the Frenkel-Kontorova chain.
We study, numerically and analytically, the classical one-dimensional Frenkel-Kontorova chain in the regime of pinned phase characterized by phonon gap. Our results show the existence of exponentially many static equilibrium configurations that are exponentially close to the energy of the ground state. The energies of these configurations form a fractal quasidegenerate band structure that is de...
متن کاملUnderdamped commensurate dynamics in a driven Frenkel-Kontorova-type model.
The dynamics of a Frenkel-Kontorova chain subject to a substrate potential with a multiple-well structure and driven by an external dc force is studied in the underdamped regime. Making a rational choice among the three inherent length scales characterizing the system allows us to consider the possible formation of commensurate structures during sliding over the complex on-site potential. We co...

Wearless friction is investigated in a simple mechanical model called Frenkel-Kontorova-Tomlinson model. We have introduced this model in [Phys. Rev. B, 53, 7539 (1996)] where the static friction has already been considered. Here the model is treated for constant sliding speed. The motion of the internal degrees of freedom is regular for small sliding velocities or weak interaction between the ...
متن کاملStatic friction on the fly: velocity depinning transitions of lubricants in motion.
The dragging velocity of a model solid lubricant confined between sliding periodic substrates exhibits a phase transition between two regimes, respectively, with quantized and with continuous lubricant center-of-mass velocity. The transition, occurring for increasing external driving force F ext acting on the lubricant, displays a large hysteresis, and has the features of depinning transitions ...
