QAtlas (QUAntum Reference Table for Exact Tests) is a Julia package providing a standardized "Ground Truth" database for benchmarking numerical methods in quantum many-body systems.
When developing new algorithms like DMRG, TEBD, or Tensor Network methods, verifying the results against known values often involves scouring old papers or re-implementing Exact Diagonalization (ED) scripts. QAtlas.jl streamlines this process by providing instant access to high-precision reference data.
- Curated Reference Data: Access exact results from ED, analytical solutions, and high-precision literature values.
- Seamless Integration: Retrieve data directly into your Julia environment for unit testing or convergence analysis.
- Comprehensive Metadata: Every data point includes information on the source (DOI), numerical precision, and the method used.
- Model Agnostic: Focuses on results rather than construction, making it compatible with any external Hamiltonian builder or simulation suite.
