We present experimental evidence that the density-scaling exponent γ is state-point dependent for the glass formers tetramethyl-tetraphenyl-trisiloxane (DC704) and 5-polyphenyl ether (5PPE). A method is proposed that from dynamic and thermodynamic properties at equilibrium estimates the value of γ. The method applies at any state point of the pressure-temperature plane, both in the supercooled and the normal liquid regimes. We find that γ is generally state-point dependent, which is confirmed by reanalyzing data for 20 metallic liquids and two model liquids.","is_dataset_classified":null,"base_score":3.58351893845611,"endowment":3.58351893845611,"datacite_reuse_total":1,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"30822033","pmcid":null,"openalex_id":"https://openalex.org/W2913420788","authors":[],"funders":[{"funder_name":"Villum Fonden","grant_id":"VKR-023455","title":null},{"funder_name":"Villum Fonden","grant_id":"16515","title":null},{"funder_name":"Villum Fonden","grant_id":"00016515","title":null}],"total_grants":3,"fwci":2.3513,"citation_percentile":0.89167607,"influential_citations":0,"citation_trend":[{"year":2019,"count":8},{"year":2020,"count":11},{"year":2021,"count":5},{"year":2022,"count":5},{"year":2023,"count":5},{"year":2024,"count":1}],"oa_status":"hybrid","license":"cc-by","oa_locations":[{"url":"http://link.aps.org/pdf/10.1103/PhysRevLett.122.055501","host_type":"journal"},{"url":"http://link.aps.org/pdf/10.1103/PhysRevLett.122.055501","host_type":"publisher"},{"url":"https://link.aps.org/article/10.1103/PhysRevLett.122.055501","host_type":"publisher"},{"url":"http://harvest.aps.org/v2/journals/articles/10.1103/PhysRevLett.122.055501/fulltext","host_type":"publisher"},{"url":"https://doi.org/10.1103/physrevlett.122.055501","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/30822033","host_type":"repository"},{"url":"https://forskning.ruc.dk/da/publications/98fdb347-8d0d-4666-8d40-8384a514b7f5","host_type":"repository"},{"url":"http://arxiv.org/abs/1807.11746","host_type":"repository"},{"url":"https://arxiv.org/pdf/1807.11746","host_type":"repository"}],"fields_of_study":["Material Dynamics and Properties","Phase Equilibria and Thermodynamics","Advanced Thermodynamics and Statistical Mechanics"],"mesh_terms":[],"keywords":["Scaling","Exponent","Statistical physics","Dynamic scaling","Dynamics (music)","State (computer science)","Physics","Point (geometry)","Liquid state","Condensed matter physics","Materials science","Thermodynamics","Computer science","Mathematics"],"sdg_mappings":[],"linked_datasets":[{"doi":"10.48550/arxiv.1807.11746","title":"Experimental evidence of a state-point dependent scaling exponent of liquid dynamics","publisher":"arXiv","resource_type":"Text"}],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-02T15:41:32.046912Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
