The paper presents an atomistic \u201ctoy model\u201d of the intra-base-pair motion which suggests that the thermodynamics may be better described by a planar vector\u2014rather than a scalar\u2014order parameter. This leads to correct estimates of melting entropy, unzipping force, hairpin opening rates, and the equilibrium constant of open\/closed base pair states during imino proton exchange.<\/jats:p>","DOI":"10.1103\/7mtw-wvkx","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T15:01:53Z","timestamp":1777042913000},"update-policy":"https:\/\/doi.org\/10.1103\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["DNA melting: Intra-base-pair dynamics and a vector generalization of the Peyrard-Bishop-Dauxois model"],"prefix":"10.1103","volume":"113","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2654-1625","authenticated-orcid":true,"given":"Nikos","family":"Theodorakopoulos","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/033m02g29","id-type":"ROR","asserted-by":"publisher"}],"name":"National Hellenic Research Foundation"},{"id":[{"id":"https:\/\/ror.org\/0546hnb39","id-type":"ROR","asserted-by":"publisher"}],"name":"Universit\u00e4t Konstanz"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16","published-online":{"date-parts":[[2026,5,11]]},"reference":[{"key":"7mtw-wvkxCc1R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.62.2755","type":"journal-article"},{"key":"7mtw-wvkxCc1R2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.47.R44","type":"journal-article"},{"key":"7mtw-wvkxCc2R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.85.6","type":"journal-article"},{"key":"7mtw-wvkxCc3R1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1014546415934","type":"journal-article"},{"key":"7mtw-wvkxCc4R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.79.2375","type":"journal-article"},{"key":"7mtw-wvkxCc5R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.82.021905","type":"journal-article"},{"key":"7mtw-wvkxCc6R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.106.048101","type":"journal-article"},{"key":"7mtw-wvkxCc6R2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.83.061923","type":"journal-article"},{"key":"7mtw-wvkxCc7R1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(18)98599-6","type":"journal-article"},{"key":"7mtw-wvkxCc8R1","doi-asserted-by":"publisher","DOI":"10.1021\/bi951907q","type":"journal-article"},{"key":"7mtw-wvkxCc8R2","unstructured":"This work, mainly on oligopolymer structures, explicitly validates the result of   [7] on the value of the average melting entropy of long polymers.","type":"other"},{"key":"7mtw-wvkxCc9R1","doi-asserted-by":"crossref","DOI":"10.1142\/11533","type":"book","volume-title":"The Statistical Physics of DNA","author":"N.
