    Abstract

    We investigate Majorana edge-mode distributions and nonlocal transport in a minimal phenomenological model of coupled Kitaev chains with prescribed Fibonacci modulation. The model is not intended as a self-consistent description of a quasiperiodic superconductor; rather, it provides a controlled setting for comparing an integer topological index with local and nonlocal conductances. Our central result is that the ν=1 sector contains distinct phases that cannot be distinguished by the topological index alone. Although these phases have the same integer invariant, they have different Majorana edge-mode distributions, which are resolved by nonlocal differential conductance. We also identify a topological phase transition induced by Fibonacci quasiperiodicity in this minimal coupled-chain setting.
