Combining them with strong, long-range dipolar interactions provides highly flexible control schemes promising even more exotic quantum phases. Recently, microwave shielding gave access to spin-polarized degenerate samples of dipolar fermionic molecules, where tunable p-wave interactions were enabled by field-linked resonances available only by compromising the shielding (due to experimental limitations). Here, we study the scattering properties of a fermionic dipolar spin mixture and show that a universal s-wave resonance is readily accessible without compromising the shielding. We develop a universal description of the tunable s-wave interaction and weakly bound tetratomic states based on the microwave-field parameters. The s-wave resonance paves the way to stable, controllable and strongly-interacting dipolar spin mixtures of deeply degenerate fermions and supports favorable conditions to reach this regime via evaporative cooling."}],"day":"14","corr_author":"1","intvolume":"         9","type":"journal_article","project":[{"name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions","_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3","grant_number":"F100403"},{"grant_number":"12078","_id":"8fa7db46-16d5-11f0-9cad-917600954daf","name":"Polarons in Lead Halide Perovskites"}],"license":"https://creativecommons.org/licenses/by/4.0/","researchdata_availability":"upon request","OA_place":"publisher","author":[{"full_name":"Li, Jinglun","id":"ff19510a-0d2c-11ef-b018-c338ad2f4325","first_name":"Jinglun","last_name":"Li"},{"last_name":"Koutentakis","first_name":"Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","full_name":"Koutentakis, Georgios"},{"last_name":"Hrast","first_name":"Mateja","full_name":"Hrast, Mateja","id":"48dbb294-2a9c-11ef-905d-f56be71f0e5d"},{"first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802"},{"first_name":"Andreas","full_name":"Schindewolf, Andreas","last_name":"Schindewolf"},{"last_name":"Al Hyder","first_name":"Ragheed","id":"d1c405be-ae15-11ed-8510-ccf53278162e","full_name":"Al Hyder, Ragheed"}],"date_created":"2026-06-21T22:02:58Z"},{"date_updated":"2026-07-14T06:33:11Z","publication_status":"published","article_number":"203401","status":"public","publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"issue":"20","publisher":"American Physical Society","month":"05","year":"2026","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"publication":"Physical Review Letters","_id":"22304","volume":136,"citation":{"chicago":"Li, Jinglun, Paul S.
