We observe that the Landauer bound, $\\langle W \\rangle \\geq kT \\ln 2$, on average dissipated work $\\langle W \\rangle$ associated to an erasure process, literally emerges from the underlying second law bound as formulated by Kelvin, $\\langle W \\rangle \\geq 0$, as consequence of a spontaneous breaking of the Crooks-Tasaki fluctuation-symmetry, that accompanies logical irreversibility. We illustrate and corroborate this insight with numerical simulations of the process of information erasure performed on a 2D Ising ferromagnet.","url_abs":"https://arxiv.org/abs/2106.07570v3","url_pdf":"https://arxiv.org/pdf/2106.07570v3.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":"spontaneous-fluctuation-symmetry-breaking-and","repo_url":"https://github.com/Buffoni/landauer_parallel","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}
