Conductance exhibits Fabry-Perot oscillation due to multiple reflections, indicating complex behavior at constrictions.
Analysis shows that magnetic fields can localize electrons on hinge states, affecting overall conductance patterns.
Finite size effects hybridize hinge states in narrow regions, leading to reflections at constriction ends.
Results remain robust against moderate disorder, highlighting the potential for experimental observation of unique interference patterns.
