Summary: Comparing transport near the 2D site-bond percolation threshold when site and bond disorder are arranged in crossed versus aligned stripe patterns.

Percolation transport depends not only on how much disorder is present, but also on how that disorder is organized in space. This experiment asks whether orthogonal stripe patterns in site occupancy and bond openness preserve more isotropic transport than aligned stripes near the 2D site-bond threshold.

The script uses GPU-accelerated simulations to compare crossed and parallel disorder geometries in a quenched setting. Its central hypothesis is that crossed stripes avoid the strongest transport collapse associated with strongly aligned anisotropy while still capturing structured, non-IID disorder.

That turns a standard percolation problem into a geometry comparison about transport rather than just connectivity. The interest is in how interacting stripe fields reshape directional motion close to criticality.

Method: GPU-accelerated site-bond percolation transport simulations with quenched stripe disorder applied orthogonally or in parallel to sites and bonds.

What is measured: Transport efficiency, isotropy or anisotropy of motion, dependence on crossed versus aligned stripes, and behavior near the site-bond threshold.
