In this paper, we explain the basic usage of $\\verb|wan2respack|$ and show its application to standard compounds of correlated materials, namely, the correlated metal SrVO$_3$ and the high-$T_{c}$ superconductor La$_2$CuO$_4$. Furthermore, we compare the low-energy effective Hamiltonians of these compounds using Wannier functions obtained by $\\verb|Wannier90|$ and those obtained by $\\verb|RESPACK|$. We confirm that both types of Wannier functions give the same Hamiltonians. This benchmark comparison demonstrates that $\\verb|wan2respack|$ correctly converts Wannier functions in the $\\verb|Wannier90|$ format into those in the $\\verb|RESPACK|$ format.","url_abs":"https://arxiv.org/abs/2302.13531v2","url_pdf":"https://arxiv.org/pdf/2302.13531v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"interface-tool-from-wannier90-to-respack","repo_url":"https://github.com/respack-dev/wan2respack","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
