Calculation of an Atomically Modulated Friction Force in Atomic-Force Microscopy.
... observed for moderate applied loads in the absence of wear and plastic deformations. For a multiatom «tip» which is commensurate with the substrate, the tip-substrate potential is proportional to the number of tip atoms at the interface, n, and so is the critical value Cerlt for nonzero friction.

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
