Using the normalization 1\/N, which corresponds to the limit p\u226ap*, provides a better linear fit of logIPR2 as a function of logp, since the pure power-law behavior is recovered more accurately in this regime. However, with this choice the extrapolated intersection with the horizontal line logIPR1=\u2212log(4N) occurs at p=p*\/2 instead of p=p*. This shift reflects the fact that the power-law behavior IPR2\u223cp4 is only an approximation, while the full perturbative expression   (11) contains an additional universal correction factor depending on p\/p*. Using the normalization 1\/(4N) incorporates this correction in the prefactor, yielding the correct intersection point at p=p* at the expense of a slightly poorer linear fit, see Fig.   1.","type":"other"},{"key":"6h5q-tv19Cc16R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.71.016129","type":"journal-article"},{"key":"6h5q-tv19Cc17R1","doi-asserted-by":"publisher","DOI":"10.1103\/wg82-f4lf","type":"journal-article"},{"key":"6h5q-tv19Cc18R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.126.040604","type":"journal-article"}],"container-title":["Physical Review E"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/link.aps.org\/article\/10.1103\/6h5q-tv19","content-type":"unspecified","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/harvest.aps.org\/v2\/journals\/articles\/10.1103\/6h5q-tv19\/fulltext","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,8]],"date-time":"2026-07-08T12:47:04Z","timestamp":1783514824000},"score":1,"resource":{"primary":{"URL":"https:\/\/link.aps.org\/doi\/10.1103\/6h5q-tv19"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,8]]},"references-count":18,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,7]]}},"URL":"https:\/\/doi.org\/10.1103\/6h5q-tv19","relation":{},"ISSN":["2470-0045","2470-0053"],"issn-type":[{"value":"2470-0045","type":"print"},{"value":"2470-0053","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,8]]},"assertion":[{"value":"2024-11-14","name":"date_received","label":"Date Received","group":{"name":"publication_dates","label":"Publication dates"}},{"value":"\u00a92026 American Physical Society.
