The five dimensional gravity model contains three bulk fields: a scalar dilaton sourcing ${\\rm Tr}F^2$, a scalar tachyon dual to $\\bar qq$ and a 4-vector dual to the baryon current $\\bar q \\gamma^{\\mu} q$. The main result is the $\\mu,T$ phase diagram of the holographic theory. A first order deconfining transition along $T_h(\\mu)$ and a chiral transition at $T_\\chi(\\mu)>T_h(\\mu)$ are found. The chiral transition is of second order for all $\\mu$. The dependence of thermodynamical quantities including the speed of sound and susceptibilities on the chemical potential and temperature is computed. A new quantum critical regime is found at zero temperature and finite chemical potential. It is controlled by an AdS$_2\\times R^3$ geometry and displays semi-local criticality.","url_abs":"https://arxiv.org/abs/1312.5199v3","url_pdf":"https://arxiv.org/pdf/1312.5199v3.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":"a-holographic-model-for-qcd-in-the-veneziano","repo_url":"https://github.com/timoalho/VQCDThermo","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}
