We apply the concept of quasi-metaparticles to the problem of non-Fermi liquids and the properties of strange metals. In particular, we point out that the quasi-metaparticle Green\u2019s function interpolates between the canonical quasi-particle Green\u2019s function and the result found in the context of the SYK model, which presents an exactly solvable model without quasiparticles. The linear dependence of resistivity with temperature is reproduced in the SYK limit. Also, the Cooper mechanism is possible in the quasi-metaparticle case. Finally, the new parameter that characterizes quasi-metaparticles can be extracted from ARPES data. Thus, the quasi-metaparticle could be a useful new concept in the study of strange metals and high-temperature superconductivity. <\/jats:p>","DOI":"10.1142\/s2810939225500017","type":"journal-article","created":{"date-parts":[[2025,3,22]],"date-time":"2025-03-22T00:12:33Z","timestamp":1742602353000},"page":"1-10","source":"Crossref","is-referenced-by-count":0,"title":["Non-Fermi liquids, strange metals and quasi-metaparticles"],"prefix":"10.1142","volume":"03","author":[{"given":"Edwin","family":"Barnes","sequence":"first","affiliation":[{"name":"Department of Physics, Virginia Tech, Blacksburg, VA 24061, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6346-8597","authenticated-orcid":false,"given":"J.
