摘要：

Stick-slip phenomenon is generally associated with a wide range of dynamical systems. Here we report a unique quasistatic form of the stick-slip characterized in terms of bursts in structural relaxation. This is demonstrated for the case of a dislocation core and its one-dimensional representation, namely, the Frenkel-Kontorova chain. The correspondence between these two is also established through the technique of dimensionality reduction.
