First, one uses phase imprinting to create a train of domain walls in a superfluid with equal number of $\uparrow$- and $\downarrow$-spins. Second, one applies a radio-frequency sweep to selectively break Cooper pairs near the domain walls and transfer the $\uparrow$-spins to a third spin state which does not interact with the $\uparrow$- and $\downarrow$-spins. The resulting FFLO state has exactly one unpaired $\downarrow$-spin in each domain wall and is stable for all values of domain-wall separation and interaction strength. We show that the protocol can be implemented with high fidelity at sufficiently strong interactions for a wide range of parameters available in present-day experimental conditions. dc.description.sponsorship National Science Foundation Grant No. PHY-1508300 dc.publisher American Physical Society (APS) dc.rights Publisher's own licence dc.title Protocol to engineer Fulde-Ferrell-Larkin-Ovchinnikov states in a cold Fermi gas dc.type Article prism.issueIdentifier 2 prism.number ARTN 023612 prism.publicationDate 2017 prism.publicationName PHYSICAL REVIEW A prism.volume 96 dc.identifier.doi 10.17863/CAM.46255 dcterms.dateAccepted 2017-07-20 rioxxterms.versionofrecord 10.1103/PhysRevA.96.023612 rioxxterms.version VoR rioxxterms.licenseref.uri http://www.rioxx.net/licenses/all-rights-reserved rioxxterms.licenseref.startdate 2017-08-14 dc.contributor.orcid Dutta, Shovan [0000-0002-3534-6920] dc.identifier.eissn 2469-9934 dc.publisher.url http://dx.doi.org/10.1103/PhysRevA.96.023612 rioxxterms.type Journal Article/Review cam.issuedOnline 2017-08-14
