The new Local Order Average-Atom (LOAA) method is rigorously derived based on statistical mechanics arguments and validated for non-stoichiometric binary 2D hexagonal crystals and 3D FeNiCr and NiAl alloys whose ground state is obtained through Monte Carlo sampling. Material properties for these alloys computed from atomistic simulations using standard interatomic potentials (IPs) exhibit a strong dependence on local ordering that is captured by simulations with effective LOAA IPs, but not the original AA method. The advantage of LOAA is that it requires smaller system sizes to achieve statistically converged results and therefore enables the simulation of complex materials, such as high-entropy alloys, at a fraction of the computational cost of standard IPs.<\/jats:p>","DOI":"10.1063\/5.0350731","type":"journal-article","created":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T10:50:23Z","timestamp":1790938223000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Local order average-atom interatomic potentials"],"prefix":"10.1063","volume":"165","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-0187-4119","authenticated-orcid":false,"given":"Chloe A.","family":"Zeller","sequence":"first","affiliation":[{"name":"Department of Aerospace Engineering and Mechanics, University of Minnesota 1 , Minneapolis, Minnesota 55455,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6392-4257","authenticated-orcid":false,"given":"Ronald E.","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Carleton University 2 , Ottawa, Ontario K1S 5B6,","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3311-6299","authenticated-orcid":false,"given":"Ellad B.","family":"Tadmor","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering and Mechanics, University of Minnesota 1 , Minneapolis, Minnesota 55455,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,10,2]]},"reference":[{"key":"2026100213410907000_c1","doi-asserted-by":"publisher","first-page":"10322","DOI":"10.1103\/physrevb.40.10322","article-title":"Application of molecular dynamics to the study of hydrogen embrittlement in Ni\u2013Cr\u2013Fe alloys","volume":"40","year":"1989","journal-title":"Phys.
