Here, we investigate the applicability of this approach for detecting entangled states in quantum systems driven out of equilibrium. We use a multipartite entanglement witness, the quantum Fisher information, to study the dynamics of a paradigmatic fermion chain undergoing a time-dependent change of the Coulomb interaction. Our results show that the quantum Fisher information is able to witness distinct signatures of multipartite entanglement both near and far from equilibrium that are robust against decoherence. We discuss implications of these findings for probing entanglement in light-driven quantum materials with time-resolved optical and x-ray scattering methods."}],"extern":"1","publication_status":"published","date_published":"2023-03-10T00:00:00Z","issue":"10","year":"2023","intvolume":"       130","volume":130,"keyword":["General Physics and Astronomy"],"external_id":{"pmid":["36962013"],"arxiv":["2209.02081"]},"publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"doi":"10.1103/physrevlett.130.106902","author":[{"last_name":"Baykusheva","first_name":"Denitsa Rangelova","id":"71b4d059-2a03-11ee-914d-dfa3beed6530","full_name":"Baykusheva, Denitsa Rangelova"},{"last_name":"Kalthoff","first_name":"Mona H.","full_name":"Kalthoff, Mona H."},{"last_name":"Hofmann","first_name":"Damian","full_name":"Hofmann, Damian"},{"full_name":"Claassen, Martin","first_name":"Martin","last_name":"Claassen"},{"full_name":"Kennes, Dante M.","last_name":"Kennes","first_name":"Dante M."},{"first_name":"Michael A.","last_name":"Sentef","full_name":"Sentef, Michael A."},{"first_name":"Matteo","last_name":"Mitrano","full_name":"Mitrano, Matteo"}],"publication":"Physical Review Letters","language":[{"iso":"eng"}],"article_number":"106902","_id":"13990","article_type":"original","citation":{"apa":"Baykusheva, D.
