Here, we introduce a minimal three-orbital tight-binding model for a single helical chain and show that chirality alone generates a momentum-dependent orbital-angular-momentum texture through Slater\u2013Koster hybridization in the local basis (pr, p\u03d5, pz), without requiring atomic spin\u2013orbit coupling. In the single-helix geometry, the radial orbital texture vanishes identically, while the azimuthal and longitudinal components remain finite and arise from the odd-in-momentum (pz, pr) and (pr, p\u03d5) sectors. As a result, the equilibrium average orbital texture vanishes by parity, although persistent-like orbital angular momentum currents may still exist and imply chirality-dependent end magnetization in a finite helix. Under an applied longitudinal electric field, the system develops a finite orbital Edelstein response, whereas the projected longitudinal orbital conductivity vanishes in the linear regime by parity. When spin degrees of freedom are included, the orbital texture acts as a source of spin polarization through orbital-to-spin transduction. Instead of being limited by the weak, natural spin\u2013orbit coupling of individual atoms, the overall spin response is driven by the much stronger interactions of overlapping molecular orbitals, making it a stronger candidate for spin injection than the conventional spin Edelstein mechanism. These results identify chirality as the minimal microscopic ingredient for generating orbital angular momentum response in one-dimensional systems and support an orbital route to spin selectivity in chiral conductors.<\/jats:p>","DOI":"10.1063\/5.0343778","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T15:52:09Z","timestamp":1786031529000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Orbital angular momentum textures and currents in a discrete helix: Equilibrium and linear response"],"prefix":"10.1063","volume":"165","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-5675-9395","authenticated-orcid":false,"given":"Danny","family":"Cordova","sequence":"first","affiliation":[{"name":"Departamento de F\u00edsica, Colegio de Ciencias e Ingenier\u00eda, Universidad San Francisco de Quito, Diego de Robles y Via Interoceanica 1 , Quito 17901,","place":["Ecuador"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4254-807X","authenticated-orcid":false,"given":"Bertrand","family":"Berche","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique et Chimie Th\u00e9oriques, CNRS - Universit\u00e9 de Lorraine, UMR 2 , 7019 Nancy,","place":["France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1566-0170","authenticated-orcid":false,"given":"Ernesto","family":"Medina","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Colegio de Ciencias e Ingenier\u00eda, Universidad San Francisco de Quito, Diego de Robles y Via Interoceanica 1 , Quito 17901,","place":["Ecuador"]},{"name":"School of Molecular Sciences, Arizona State University 3 , 551E University Dr., Tempe, Arizona 85281,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"key":"2026080611520114800_c1","doi-asserted-by":"publisher","first-page":"323","DOI":"10.1103\/revmodphys.76.323","volume":"76","year":"2004","journal-title":"Rev.
