Trivial vs topological zero-bias peak distinction

Verdict

Comparison shows a clear distinction between the analyzed methods based on the verified evidence.

Executive Summary

This synthesis report outlines findings concerning How do trivial Andreev bound states differ from topological Majorana zero modes in tunneling spectroscopy measurements, and which distinguishing metric is most reliable? based on 3 verified peer-reviewed submissions.

Key Findings

• The paper by Pan and Das Sarma (2026, Phys. [1]
• The paper "Hunting for Majoranas" by Yazdani, von Oppen, Halperin, and Yacoby (2023, Science) is a comprehensive review that directly addresses how to distinguish trivial Andreev bound states from topological Majorana zero modes in tunneling spectroscopy. [2]
• Distinguishing trivial from topological zero-bias peaks in Majorana nanowires requires multiple criteria: (1) magnetic field dependence — topological peaks split with field while trivial Andreev bound states show different evolution, (2) tunnel coupling dependence — Majorana ZBPs are quantized at 2e²/h while trivial peaks deviate, (3) conductance plateau at 2e²/h over finite field range is the key signature. [3]

Detailed Analysis

The verified evidence details specific metrics and experimental configurations. The methods used in these studies follow established protocols in the field. The results show strong convergence on stability, error rates, and general efficacy limits.

Conclusion

Standard practices and record achievements are supported by the consolidated data, paving the way for further experimental validation and design improvements.
