We show that the same Gaussian density that regularizes electrostatics also generates a finite dispersion damping function through the damped dipole\u2013dipole tensor, while overlap-based forms provide a compatible finite exchange repulsion. The resulting Gaussian van der Waals potential, GVDW, has the form Uvdw = Urep \u2013 C6F(\u03bar)\/r6, recovering the dipole\u2013dipole 1\/r6 dispersion tail at long range. As a minimal proof of concept in a polarizable Gaussian-density water model, with only two O\u2013O repulsive parameters refitted, GVDW gives stable liquid simulations and shifts the close-contact O\u2013O radial distribution function toward experiment relative to the Lennard-Jones potential. The result suggests a route to nonbonded potentials organized around a common finite-density picture.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c02430","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T21:01:28Z","timestamp":1791320488000},"page":"12056-12062","source":"Crossref","is-referenced-by-count":0,"title":["A Density-Consistent, Finite van der Waals Potential\nfrom Gaussian Atomic Densities"],"prefix":"10.1021","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-4478-8477","authenticated-orcid":true,"given":"Zhen","family":"Huang","sequence":"first","affiliation":[{"name":"University of California , , , ,","place":["Irvine, California, United States, 92697"]},{"name":"University of California , , , ,","place":["Irvine, California, United States, 92697"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6346-8271","authenticated-orcid":true,"given":"Ray","family":"Luo","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Irvine, California, United States, 92697"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3793-5099","authenticated-orcid":true,"given":"Yong","family":"Duan","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Davis, California, United States, 95616"]},{"name":"University of California , , , ,","place":["Davis, California, United States, 95616"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,6]]},"reference":[{"key":"2026102208022340700_cit1","doi-asserted-by":"publisher","first-page":"6141","DOI":"10.1063\/1.468398","article-title":"Dynamical fluctuating charge force\nfields: Application to liquid water","volume":"101","author":"Rick","year":"1994","journal-title":"J.
