Theoretical analysis of Coulomb blockade transport in realistic Majorana nanowire devices. Develops a model accounting for finite-length effects, orbital contributions, and quasi-Majorana states that can mimic topological signatures. Important for interpreting experimental Majorana signatures and distinguishing genuine topological zero modes from trivial near-zero-energy states.
