Current implementations are based on the interplay between local polarization and propagation direction of light in nanophotonic structures. In this manuscript, we propose an alternative platform based on coupling quantum emitters to a photonic sawtooth lattice, a one-dimensional model with an effective flux per plaquette introduced by complex tunnelings. We study the dynamics emerging from such structured photonic bath and find the conditions to obtain quasiperfect directional emission when the emitters are resonant with the band. In addition, we find that the photons in this bath can also mediate complex emitter-emitter interactions tunable in range and phase when the emitters transition frequencies lie within a band gap. Since these effects do not rely on polarization, we propose an implementation based on circuit QED to observe this physics. 000099260 536__ $$9info:eu-repo/grantAgreement/ES/CSIC/PTI-001$$9info:eu-repo/grantAgreement/EC/H2020/742102/EU/Quantum Emitters in non-conventional baths/QUENOCOBA$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 742102-QUENOCOBA$$9info:eu-repo/grantAgreement/ES/MICINN/PGC2018-094792-B-I00 000099260 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000099260 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000099260 700__ $$aWan, C. 000099260 700__ $$0(orcid)0000-0003-4478-1948$$aZueco, D.$$uUniversidad de Zaragoza 000099260 700__ $$aGonzalez-Tudela, A. 000099260 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
