We report a study of this system by using ab initio molecular dynamics simulations, which recover the same kind of behavior, and we analyze it in terms of a theoretical approach, which clarifies its origin. We show that the previous interpretation has been induced by the unphysical extension of the diffusive model to short times. Moreover, we also find that quite different liquid metals, such as Si and Mg, also exhibit a similar behavior as Hg, with the only difference being in the time scales involved due to the different masses and interactions.<\/jats:p>","DOI":"10.1063\/1.3020717","type":"journal-article","created":{"date-parts":[[2008,11,7]],"date-time":"2008-11-07T23:32:40Z","timestamp":1226100760000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":4,"title":["On the behavior of single-particle dynamic properties of liquid Hg and other metals"],"prefix":"10.1063","volume":"129","author":[{"given":"Luis E.","family":"Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Universidad de Valladolid 1 Departamento de F\u00edsica Te\u00f3rica, , 47011 Valladolid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David J.","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Universidad de Valladolid 1 Departamento de F\u00edsica Te\u00f3rica, , 47011 Valladolid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00e1zaro","family":"Calder\u00edn","sequence":"additional","affiliation":[{"name":"Universidad de Valladolid 1 Departamento de F\u00edsica Te\u00f3rica, , 47011 Valladolid, Spain"},{"name":"Queen\u2019s University 2 Department of Physics, , Kingston, K7L 3N6 Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sedat","family":"\u015eeng\u00fcl","sequence":"additional","affiliation":[{"name":"Trakya University 3 Department of Physics, , TR-2030 Edirne, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2008,11,7]]},"reference":[{"key":"2023062604084812900_c1","doi-asserted-by":"publisher","first-page":"215504","DOI":"10.1103\/PhysRevLett.87.215504","volume":"87","year":"2001","journal-title":"Phys.
