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."}],"scopus_import":"1","fulldoi":"https://doi.org/10.1038/s42005-026-02578-8","doi":"10.1038/s42005-026-02578-8","publication_status":"published","external_id":{"arxiv":["2506.23318"]},"project":[{"name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions","grant_number":"F100403","_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3"},{"_id":"8fa7db46-16d5-11f0-9cad-917600954daf","grant_number":"12078","name":"Polarons in Lead Halide Perovskites"}],"acknowledgement":"J.-L.Li thanks Gaoren Wang for valuable discussions on the absorbing boundary condition.

In optical fields, where multiple vortices coexist, the local nature of vortex OAM and the absence of a common rotation axis make the total OAM of the field difficult to quantify. Here, we introduce the R index—a metric that captures the intrinsic OAM content of any structured optical field, from pure Laguerre–Gaussian modes to arbitrary multi vortex superpositions. Not only does this metric quantify the total OAM, it also assesses field purity, providing insight into the fidelity and robustness of the OAM generation. By unifying OAM characterization into a single figure of merit, the R index enables direct comparison across diverse beam profiles and facilitates the identification of optimal configurations for both foundational studies and applied technologies.","lang":"eng"}],"doi":"10.1088/2515-7647/ae3506","OA_type":"hybrid","status":"public","arxiv":1,"type":"journal_article","month":"03","title":"The R-index: A universal metric for evaluating OAM content and mode purity in optical fields","date_published":"2026-03-10T00:00:00Z","citation":{"short":"M.

We map how interaction strength, lattice depth, lattice wave number, and pulse duration reshape the diffraction pattern, leading to an interaction-dependent population redistribution in real and momentum space. By comparing the exact dynamics to an impulsive sudden-approximation description, we delineate the parameter regimes where it remains accurate and those, notably at strong attraction and small lattice wave number, where it fails.

In particular, we consider coherently coupled spin states with an external field, where only one spin component interacts with the bath, enabling light dressing of the impurity and spin-dependent bath-impurity interactions. Through detailed comparisons with ab-initio many-body simulations, we demonstrate that the composite system is accurately described by a simplified effective Hamiltonian. The latter builds upon previously developed effective potential approaches in the absence of light dressing. It can be used to extract the impurity energy, residue, effective mass, and anharmonicity induced by the phononic dressing. Light-dressing is shown to increase the polaron residue, undressing the impurity from phononic excitations because of strong spin coupling. For strong repulsions, previously shown to trigger dynamical Bose polaron decay (a phenomenon called temporal orthogonality catastrophe), it is explained that strong light-dressing stabilizes a repulsive polaron-dressed state. Our results establish the effective Hamiltonian framework as a powerful tool for exploring strongly interacting polaronic systems and corroborating forthcoming experimental realizations.","lang":"eng"}],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"fulldoi":"https://doi.org/10.21468/SciPostPhys.19.4.093","scopus_import":"1","doi":"10.21468/SciPostPhys.19.4.093","department":[{"_id":"MiLe"}],"acknowledgement":"G.M.K. has received funding by the Austrian Science Fund (FWF)\r\n[DOI: 10.55776/F1004].

These transitions are governed by conical intersections arising from the pseudo Jahn-Teller effect, dynamically shaping the impurity's motion through the bath. Using ab initio simulations via the multilayer multiconfiguration time-dependent Hartree method and a multichannel Born-Oppenheimer framework, we track the impurity's evolution and directly prove the dynamical manifestation of the pseudo Jahn-Teller effect. We analyze two key scenarios: (i) a small initial shift, where a single avoided crossing drives transitions, and (ii) a large shift, where multiple avoided crossings lead to enhanced nonadiabaticity, self-trapping, and energy redistribution.

Increasing repulsion leads to the appearance of nonadiabatic couplings between the fast bath and slow impurity degrees of freedom, which reduce the parity symmetry of the latter according to the pseudo Jahn-Teller effect. The presence of this mechanism is associated to a conical intersection involving the impurity position and the inverse of the interaction strength, which acts as a synthetic dimension. We elucidate the presence of these effects via a detailed ground-state analysis involving the comparison of ab initio fully correlated simulations with effective models. Our study suggests ultracold atomic ensembles as potent emulators of complex molecular phenomena.","lang":"eng"}],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"doi":"10.1103/physrevresearch.6.013257","department":[{"_id":"MiLe"}],"project":[{"name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413","call_identifier":"H2020","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c"}],"acknowledgement":"This work has been funded by the Cluster of Excellence “Advanced Imaging of Matter” of the Deutsche Forschungsgemeinschaft (DFG) - EXC 2056 - Project ID 390715994.\r\nG.M.K. gratefully acknowledges funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 101034413.","language":[{"iso":"eng"}],"day":"01","publication":"Physical Review Research","article_processing_charge":"Yes","_id":"15181","publisher":"American Physical Society","oa_version":"Published Version","has_accepted_license":"1","oa":1,"quality_controlled":"1","article_number":"013257","DOAJ_listed":"1","date_created":"2024-03-25T08:57:07Z","file":[{"creator":"dernst","checksum":"4e0e58d1f58386fb016284c84db2a300","access_level":"open_access","file_size":2207067,"date_updated":"2024-03-25T09:24:55Z","content_type":"application/pdf","success":1,"file_id":"15183","file_name":"2024_PhysicalReviewResearch_Becker.pdf","date_created":"2024-03-25T09:24:55Z","relation":"main_file"}],"article_type":"original","ddc":["530"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"last_name":"Becker","first_name":"A.","full_name":"Becker, A."},{"id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis","first_name":"Georgios","full_name":"Koutentakis, Georgios"},{"full_name":"Schmelcher, P.","first_name":"P.","last_name":"Schmelcher"}],"ec_funded":1},{"publication":"Physical Review Research","_id":"18087","publisher":"American Physical Society","oa_version":"Published Version","article_processing_charge":"Yes","corr_author":"1","day":"10","language":[{"iso":"eng"}],"related_material":{"record":[{"id":"19048","status":"public","relation":"dissertation_contains"}]},"APC_amount":"3028,31 EUR","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"orcid":"0000-0003-4074-2570","first_name":"Mikhail","full_name":"Maslov, Mikhail","id":"2E65BB0E-F248-11E8-B48F-1D18A9856A87","last_name":"Maslov"},{"id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis","first_name":"Georgios","full_name":"Koutentakis, Georgios"},{"last_name":"Hrast","id":"48dbb294-2a9c-11ef-905d-f56be71f0e5d","full_name":"Hrast, Mateja","first_name":"Mateja"},{"last_name":"Heckl","full_name":"Heckl, Oliver H.","first_name":"Oliver H."},{"last_name":"Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","first_name":"Mikhail","orcid":"0000-0002-6990-7802"}],"ec_funded":1,"file":[{"file_id":"18125","date_updated":"2024-09-23T09:46:20Z","content_type":"application/pdf","success":1,"relation":"main_file","file_name":"2024_PhysicalReviewResearch_Maslov.pdf","date_created":"2024-09-23T09:46:20Z","checksum":"8f744d94956a1683b473b1cf9b411a37","creator":"dernst","file_size":1563824,"access_level":"open_access"}],"ddc":["530"],"article_type":"original","OA_place":"publisher","article_number":"033277","DOAJ_listed":"1","date_created":"2024-09-18T11:43:16Z","oa":1,"has_accepted_license":"1","quality_controlled":"1","date_published":"2024-09-10T00:00:00Z","title":"Theory of angular momentum transfer from light to molecules","intvolume":"         6","citation":{"apa":"Maslov, M., Koutentakis, G., Hrast, M., Heckl, O.

The light-matter interaction Hamiltonian we derive is expressed through couplings between spherical gradients of the electric field and the (transition) electric multipole moments of a particle of any nontrivial rotation point group. Our model can therefore accommodate an arbitrary complexity of the molecular and electric field structure, and it can be straightforwardly extended to atoms or nanostructures. Applying this framework to rovibrational spectroscopy of molecules, we uncover the general mechanism of angular momentum exchange between the spin and orbital angular momenta of light, molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions that are considered forbidden in the case of nonhelical light. We discuss the experimental requirements for the observation of these forbidden transitions in state-of-the-art spatially resolved spectroscopy measurements.","lang":"eng"}],"scopus_import":"1","fulldoi":"https://doi.org/10.1103/physrevresearch.6.033277","doi":"10.1103/physrevresearch.6.033277","publication_status":"published","external_id":{"arxiv":["2310.00095"]}},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"first_name":"Georgios","full_name":"Koutentakis, Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis"},{"full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543","first_name":"Areg","last_name":"Ghazaryan","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0002-6990-7802","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","last_name":"Lemeshko"}],"ec_funded":1,"file":[{"file_name":"2023_PhysReviewResearch_Koutentakis.pdf","date_created":"2023-11-07T07:52:46Z","relation":"main_file","content_type":"application/pdf","date_updated":"2023-11-07T07:52:46Z","success":1,"file_id":"14493","access_level":"open_access","file_size":1127522,"creator":"dernst","checksum":"cb8de8fed6e09df1a18bd5a5aec5c55c"}],"article_type":"original","ddc":["530"],"article_number":"043016","date_created":"2023-11-05T23:00:53Z","has_accepted_license":"1","oa":1,"quality_controlled":"1","publication":"Physical Review Research","article_processing_charge":"Yes","publisher":"American Physical Society","_id":"14486","oa_version":"Published Version","corr_author":"1","day":"05","language":[{"iso":"eng"}],"project":[{"grant_number":"101034413","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020","name":"IST-BRIDGE: International postdoctoral program"},{"name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020","_id":"2688CF98-B435-11E9-9278-68D0E5697425","grant_number":"801770"}],"acknowledgement":"We thank Zh.

In the nonperturbative regime, where our theory cannot be reduced to any of the earlier models, we reveal that the polaron is characterized by large coherence length and a roughly tenfold increase of the effective mass as compared to the bare mass.

Within an effective potential model, the impurity is strongly confined by the host excitations which can even overcome the impurity-medium repulsion leading to a self-localized quasi-particle state. The phase diagram of the attractive and self-bound repulsive magnetic polaron, repulsive non-magnetic (Fröhlich-type) polaron and impurity-medium phase-separation regimes is explored with respect to the Rabi-coupling between the spin components, spin–spin interactions and impurity-medium coupling. The residue of such magnetic polarons decreases substantially in both strong attractive and repulsive branches with strong impurity-spin interactions, illustrating significant dressing of the impurity. The impurity can be used to probe and maneuver the spin polarization of the magnetic medium while suppressing ferromagnetic spin–spin correlations. It is shown that mean-field theory fails as the spinor gas approaches immiscibility since the generated spin-wave excitations are prominent.
