[{"abstract":[{"text":"Quantum control of the many-body wavefunction is a central challenge in quantum materials research, as it could yield a precise control knob to manipulate emergent phenomena. Floquet engineering, the coherent dressing of quantum states with periodic non-resonant optical fields, has become an important strategy for quantum control. Most applications to solid-state systems have targeted weakly interacting or single-ion states, leaving the manipulation of many-body wavefunctions largely unexplored. Here we use Floquet engineering to achieve quantum control of a strongly correlated Hubbard exciton in the one-dimensional Mott insulator Sr2CuO3. A non-resonant mid-infrared optical field coherently dresses the exciton wavefunction, driving its rotation between bright and dark states. We use resonant third-harmonic generation to quantify ultrafast π/2 rotations on the Bloch sphere spanned by these exciton states. Our work advances the quest towards programmable control of correlated states and exciton-based quantum sensing.","lang":"eng"}],"external_id":{"arxiv":["2601.20695 "]},"author":[{"id":"71b4d059-2a03-11ee-914d-dfa3beed6530","orcid":"0000-0002-7438-1139","full_name":"Baykusheva, Denitsa Rangelova","last_name":"Baykusheva","first_name":"Denitsa Rangelova"},{"full_name":"Carmichael, Deven","last_name":"Carmichael","first_name":"Deven"},{"last_name":"Weber","first_name":"Clara S.","full_name":"Weber, Clara S."},{"first_name":"I.

Superconductivity was also recently observed in the bilayer and trilayer Ruddlesden-Popper nickelates, the electronic structure of which is expected to differ from that of cuprates and square-planar nickelates. Here we study how electronic structure and magnetic interactions evolve with the number of layers, 𝑛, in thin film Ruddlesden-Popper nickelates Nd𝑛+1⁢Ni𝑛⁢O3⁢𝑛+1 with 𝑛=1,3, and 5 using resonant inelastic x-ray scattering (RIXS). The RIXS spectra are consistent with a high-spin |3⁢𝑑8⁢ 𝐿̲⟩ electronic configuration, resembling that of La2−𝑥⁢Sr𝑥⁢NiO4 and the parent perovskite, NdNiO3. The magnetic excitations soften to lower energy in the structurally self-doped, higher-𝑛 films. Our observations confirm that structural tuning is an effective route for altering electronic properties, such as magnetic superexchange, in this prominent family of materials."}],"author":[{"last_name":"Tenhuisen","first_name":"Sophia F.R.","full_name":"Tenhuisen, Sophia F.R."},{"last_name":"Pan","first_name":"Grace A.","full_name":"Pan, Grace A."},{"first_name":"Qi","last_name":"Song","full_name":"Song, Qi"},{"id":"71b4d059-2a03-11ee-914d-dfa3beed6530","full_name":"Baykusheva, Denitsa Rangelova","last_name":"Baykusheva","first_name":"Denitsa Rangelova"},{"last_name":"Ferenc Segedin","first_name":"Dan","full_name":"Ferenc Segedin, Dan"},{"last_name":"Goodge","first_name":"Berit H.","full_name":"Goodge, Berit H."},{"full_name":"Paik, Hanjong","last_name":"Paik","first_name":"Hanjong"},{"full_name":"Pelliciari, Jonathan","last_name":"Pelliciari","first_name":"Jonathan"},{"first_name":"Valentina","last_name":"Bisogni","full_name":"Bisogni, Valentina"},{"full_name":"Gu, Yanhong","first_name":"Yanhong","last_name":"Gu"},{"full_name":"Agrestini, Stefano","first_name":"Stefano","last_name":"Agrestini"},{"first_name":"Abhishek","last_name":"Nag","full_name":"Nag, Abhishek"},{"full_name":"García-Fernández, Mirian","first_name":"Mirian","last_name":"García-Fernández"},{"full_name":"Zhou, Ke Jin","last_name":"Zhou","first_name":"Ke Jin"},{"last_name":"Kourkoutis","first_name":"Lena F.","full_name":"Kourkoutis, Lena F."},{"full_name":"Brooks, Charles M.","last_name":"Brooks","first_name":"Charles M."},{"full_name":"Mundy, Julia A.","last_name":"Mundy","first_name":"Julia A."},{"full_name":"Dean, Mark P.M.","first_name":"Mark P.M.","last_name":"Dean"},{"last_name":"Mitrano","first_name":"Matteo","full_name":"Mitrano, Matteo"}],"external_id":{"arxiv":["2504.07268"]},"oa":1,"oa_version":"None","_id":"19639"},{"status":"public","date_created":"2025-01-27T14:29:20Z","doi":"10.1038/s41567-024-02401-7","day":"01","type":"journal_article","title":"Through the slopes of a light-induced phase transition","issue":"5","OA_type":"closed access","scopus_import":"1","publication_identifier":{"issn":["1745-2473"],"eissn":["1745-2481"]},"corr_author":"1","publication":"Nature Physics","quality_controlled":"1","article_processing_charge":"No","publisher":"Springer Nature","language":[{"iso":"eng"}],"month":"05","intvolume":"        20","citation":{"mla":"Baykusheva, Denitsa Rangelova. “Through the Slopes of a Light-Induced Phase Transition.” <i>Nature Physics</i>, vol. 20, no. 5, Springer Nature, 2024, pp. 684–85, doi:<a href=\"https://doi.org/10.1038/s41567-024-02401-7\">10.1038/s41567-024-02401-7</a>.","chicago":"Baykusheva, Denitsa Rangelova. “Through the Slopes of a Light-Induced Phase Transition.” <i>Nature Physics</i>.
