Here, we report an extraordinary spin-split dispersion effect of leaky surface plasmons in an inversion-symmetric plasmonic crystal. Momentum domain polarization analysis identified a transverse momentum-dependent linear birefringence\u2013linear dichroism (geometric LB\u2013LD) effect responsible for this phenomena. It is demonstrated that evolution of strong geometrical phase gradient due to the geometric LB\u2013LD effect mediates the spin-split dispersion in inversion symmetric plasmonic metasurface through spin (circular polarization)-dependent transverse momentum. This unconventional SOI phenomena offers a new paradigm of spin-based dispersion engineering and spin-controlled nano-optical functionalities by encompassing the forbidden class of symmetric metastructures in the realm of spin optics.<\/jats:p>","DOI":"10.1088\/1361-6633\/ae8695","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T22:51:00Z","timestamp":1783378260000},"page":"070501","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Rashba-like spin splitting in inversion symmetric plasmonic metasurface"],"prefix":"10.1088","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-1436-600X","authenticated-orcid":true,"given":"Sujit","family":"Rajak","sequence":"first","affiliation":[{"name":"Indian Institute of Science Education and Research Kolkata"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nishkarsh","family":"Kumar","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Kanpur"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6972-6970","authenticated-orcid":true,"given":"Dheeraj","family":"Yadav","sequence":"additional","affiliation":[{"name":"Indian Institute of Science Education and Research Kolkata"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3173-0475","authenticated-orcid":true,"given":"Suman","family":"Mandal","sequence":"additional","affiliation":[{"name":"Indian Institute of Science Education and Research Kolkata"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeeban K","family":"Nayak","sequence":"additional","affiliation":[{"name":"Swiss Federal Institute of Technology Lausanne (EPFL)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2443-9125","authenticated-orcid":true,"given":"Ayan","family":"Banerjee","sequence":"additional","affiliation":[{"name":"Indian Institute of Science Education and Research Kolkata"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7168-8549","authenticated-orcid":true,"given":"Subhasish","family":"Dutta Gupta","sequence":"additional","affiliation":[{"name":"Indian Institute of Science Education and Research Kolkata"},{"name":"Tata Institute of Fundamental Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9574-3119","authenticated-orcid":true,"given":"Olivier","family":"Martin","sequence":"additional","affiliation":[{"name":"Swiss Federal Institute of Technology Lausanne (EPFL)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3967-2117","authenticated-orcid":true,"given":"Nirmalya","family":"Ghosh","sequence":"additional","affiliation":[{"name":"Indian Institute of Science Education and Research Kolkata"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2026,7,14]]},"reference":[{"key":"ropae8695bib1","volume":"vol 191","author":"Roland","year":"2003","type":"book"},{"key":"ropae8695bib2","doi-asserted-by":"publisher","first-page":"796","DOI":"10.1038\/nphoton.2015.201","type":"journal-article","article-title":"Spin\u2013orbit interactions of light","volume":"9","author":"Bliokh","year":"2015","journal-title":"Nat.
