Quantum Spin System Ground State Data for 'Many-body quantum sign structures' Paper

Raw data supporting the publication 'Many-body quantum sign structures as non-glassy Ising models' by Westerhout, Katsnelson, and Bagrov. The data were used to draw conclusions and generate figures for the paper, which studies sign structures of frustrated quantum spin systems. The repository is authored by Tom Westerhout from Radboud University Nijmegen.

Use Cases

• Testing algorithms for reconstructing wave function signs from amplitudes based on the described mapping to an auxiliary Ising model.
• Benchmarking deterministic combinatorial solvers for Ising models derived from quantum systems.
• Analyzing the relationship between frustration in quantum spin systems and their corresponding classical Ising models as described in the paper.

Strengths

• Data is directly tied to a published research paper, providing verifiable context.
• The description outlines a specific methodological approach for sign structure analysis.

Limitations

• Row count, file formats, and column definitions are unknown, limiting suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Last update date is unknown; freshness unverified.
