Simulated Lesser Green's Functions for Correlated Systems via tDMRG

Ta Tang's dataset contains simulated lesser Green's functions computed using the time-dependent density matrix renormalization group method. The 4.4 MB dataset, last updated in May 2026, supports the paper 'Improving Spectral Resolution from Real-time Evolution for Correlated Systems'. Data files are provided in NPY and MD formats.

Use Cases

• Benchmarking spectral function extraction algorithms based on simulated Green's functions.
• Studying real-time evolution in correlated quantum models based on tDMRG data.
• Developing methods for improving frequency resolution from time-domain data as referenced in the paper.

Strengths

• Data is directly tied to a specific research paper, providing clear context.
• Files are provided in the NPY format, which is efficient for numerical array storage.
• Dataset is openly available under a CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 4.4 MB, which may limit the scope of analysis.
