Comment on "Percolation Thresholds in the Three-Dimensional Stick System"

TL;DR

This paper clarifies a common mistake in previous 3D stick percolation studies, corrects the isotropic configuration generation, and confirms the validity of the excluded volume theory through new Monte Carlo simulations.

Contribution

It identifies and corrects a classical mistake in generating isotropic configurations in 3D stick percolation models and validates the excluded volume theory with new simulations.

Findings

Corrected isotropic configuration generation method

Systematic deviations explained and addressed

Monte Carlo simulations confirm excluded volume theory

Abstract

We discuss a classical mistake, made in earlier publications on the stick percolation problem in 3D, for generating the right isotropic configuration of sticks. We explain the observed systematic deviations from the excluded volume rule. New MC simulations considered by us confirm nicely the applicability of the excluded volume theory.
