We demonstrate that short-ranged charge–rotor interactions lead to long-range ferroelectric ordering of rotors, which strongly affects the carrier mobility. 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. These results are in good agreement with other theoretical predictions for ferroelectric polarons. Our model establishes a general phenomenological framework for ferroelectric polarons providing the starting point for future studies of their role in the transport properties of hybrid organic-inorganic perovskites.","lang":"eng"}],"date_updated":"2023-11-07T07:53:39Z","volume":5,"date_created":"2023-11-05T23:00:53Z","file_date_updated":"2023-11-07T07:52:46Z"},{"project":[{"name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020","grant_number":"101034413"}],"language":[{"iso":"eng"}],"issue":"4","publication_identifier":{"issn":["2643-1564"]},"quality_controlled":"1","doi":"10.1103/PhysRevResearch.5.043039","department":[{"_id":"MiLe"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Physical Society","ec_funded":1,"article_processing_charge":"Yes","scopus_import":"1","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"publication":"Physical Review Research","file":[{"creator":"dernst","file_size":2362158,"content_type":"application/pdf","relation":"main_file","file_name":"2023_PhysReviewResearch_Becker.pdf","success":1,"access_level":"open_access","date_created":"2023-12-11T10:49:07Z","checksum":"ee31c0d0de5d1b65591990ae6705a601","file_id":"14672","date_updated":"2023-12-11T10:49:07Z"}],"day":"12","author":[{"full_name":"Becker, J.

We assume that our finite fermionic system is close to fully spin polarized while being doped by a hole and an impurity fermion with opposite spin. Our setup involves ferromagnetic couplings among the particles in different bands, leading to the development of strong spin-transport correlations in an intermediate interaction regime. Interactions are then strong enough to lift the degeneracy among singlet and triplet spin configurations in the well of the spin impurity but not strong enough to prohibit hole-induced magnetic excitations to the singlet state. Despite the strong spin-hole correlations, the system exhibits spin-charge deconfinement allowing for long-range entanglement of the spatial and spin degrees of freedom.","lang":"eng"}],"type":"journal_article","month":"10","oa_version":"Published Version","date_created":"2023-12-10T23:00:58Z","file_date_updated":"2023-12-11T10:49:07Z","volume":5}]
