Universality in the tape-peeling trace

TL;DR

This paper demonstrates that the pattern formation in tape-peeling traces belongs to the 1-dimensional directed percolation universality class, supported by both a mathematical model and experimental data re-analysis.

Contribution

It establishes the universality class of tape-peeling patterns, connecting experimental observations and a mathematical model within the 1D directed percolation framework.

Findings

The tape-peeling model belongs to the 1D directed percolation universality class.

Experimental data re-analysis supports the universality classification.

Patterns in tape-peeling traces exhibit critical behavior consistent with directed percolation.

Abstract

Spatiotemporal patterns, which are of interest in statistical physics and nonlinear dynamics, form on the tape-peeling trace. Recently, we have proposed a mathematical model to describe these pattern formation in the tape-peeling trace. In this paper, we further investigate the tape-peeling model from the perspective of its universality class. We confirm that our model belongs to the 1-dimensional directed percolation universality class. Furthermore, the experimental results from a previous study are re-analyzed, and it is suggested that the tape-peeling trace can also be classified within the 1-dimensional directed percolation universality class.
