Fractional Quantum Hall States in Mixed-Stacked Pentalayer Graphene

Replication data for a study reporting a cascade of even-denominator fractional quantum Hall states at fillings ν = -5/2, -7/2, -9/2, -11/2, and -13/2 in mixed-stacked pentalayer graphene. The dataset, authored by Kai Liu and hosted on Harvard Dataverse, was last updated on 2026-04-20. It supports the identification of quantum phase transitions and possible Moore–Read-type pairing.

Use Cases

• Analyzing displacement-field tunability of even-denominator states based on the experimental results described.
• Investigating quantum phase transitions between even-denominator states, magnetic Bloch states, and composite Fermi liquids based on the reported field tuning.
• Supporting numerical calculations for Moore–Read-type pairing in even-denominator states as mentioned in the description.
• Studying the interplay of quadratic and cubic band dispersions in mixed-stacked graphene as a platform for correlated topological phases.

Strengths

• Data supports the observation of five specific even-denominator states (ν = -5/2, -7/2, -9/2, -11/2, -13/2) alongside numerous odd-denominator states.
• Results demonstrate clear displacement-field tunability and identification of continuous quantum phase transitions.
• Dataset is associated with a study published in a scientific context and hosted on an authoritative platform (Harvard Dataverse).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Direct experimental probes of exchange statistics for the reported states are noted as important for future work.
