The past decade has seen intense focus on realising hybrid semiconducting-superconducting nanowires which exhibit Majorana Zero Modes (MZMs) in a nontrivial topological phase. This has been particularly motivated by the non-Abelian statistics of MZMs and their application in performing topological quantum computation. A quantised zero-bias peak in conductance transport measurements is seen as the hallmark of MZMs. However, it has been proven that other physical phenomena, most notably disorder-induced Andreev bound states, can mimic these same signatures. This poses a significant challenge to detecting MZMs in existing experiments. Here we present our investigations of alternative experimental strategies for identifying nontrivial topological phases.
