Here we theoretically investigate the evolution of the subharmonic gap structure in spinful Josephson junctions. Spin mixing introduced by the spin-orbit coupling opens avoided crossings in the dispersion relation of the leads, which, as we demonstrate, subsequently results in pronounced multiple Andreev reflection features in the conductance traces. We analyze how these features evolve under an external magnetic field and explain that their visibility in conductance is governed by the spin polarization of the bands.<\/jats:p>","DOI":"10.1038\/s41598-026-47507-5","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T15:56:46Z","timestamp":1777564606000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of spin-orbit coupling and Zeeman interaction on the multiple Andreev reflections subharmonic gap structure in nanoscopic Josephson junctions"],"prefix":"10.1038","volume":"16","author":[{"given":"Dibyendu","family":"Kuiri","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge Huamani","family":"Correa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Biborski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142 Piotr","family":"Nowak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"47507_CR1","doi-asserted-by":"publisher","first-page":"434","DOI":"10.1103\/PhysRev.184.434","volume":"184","author":"LJ Barnes","year":"1969","unstructured":"Barnes, L.
