Square Well Lines Potential: Two sticks of length $L$ (drawn in red) are painted with square well matter. $s_{1}, \, s_{2}$ are the inner and outer well boundaries; $\theta_{1,2}$, $\phi$ ($\rightarrow \; \vec{e}_{1}, \vec{e}_{2}$) describe the orientations; $z_{12}$ is the only relevant coordinate (= center-center distance.)
