Quantum Capacitance Oscillations for Majorana and Quasi-Majorana Mode Analysis

Flux-dependent quantum capacitance oscillations provide a mechanism for fermion parity readout in semiconductor-superconductor heterostructures. The 1.6 MB dataset contains simulation results for various system parameters, published by author Tudor Stanescu in March 2026. It supports analysis of topological Majorana zero modes, partially-separated Majorana modes, and quasi-Majorana modes in trivial phases.

Use Cases

• Analyze the relationship between magnetic flux (first column) and quantum capacitance to distinguish topological MZMs from trivial quasi-Majorana modes.
• Map the topological invariant (third column in Fig4Left data) against Zeeman field and chemical potential to identify phase boundaries.
• Correlate energy (third column in Fig4Right data) and localization length (fourth column) with system parameters to study mode hybridization.
• Use fermion parity-dependent oscillation phase shifts to benchmark proposed readout schemes for topological qubits.

Strengths

• Data is structured with clear column definitions for key physical quantities like magnetic flux, Zeeman field, and chemical potential.
• Published under a permissive CC-BY-4.0 license, enabling reuse and sharing.
• Dataset is focused on a specific, recent experimental advance in quantum capacitance measurement.

Limitations

• The dataset is small (1.6 MB), limiting the scope for large-scale statistical or machine learning analysis.
• Specific row counts and the number of individual simulation runs are not provided, making reproducibility assessment difficult.
• Data represents theoretical simulation outputs, not direct experimental measurements, which may include model-specific assumptions.
