The corresponding&amp;#xD;instantaneous energy dispersion reveals a highly nonlinear term that mirrors the high-frequency&amp;#xD;excitations underlying the non-equilibrium transport quantities. We stress out that the instan-&amp;#xD;taneous energy levels dynamics carry much information on HHG and thereby provide a simplified&amp;#xD;understanding of the effect. Further, we exploit the present approach to predict the emergence of&amp;#xD;tunable integer and fractional high harmonics in the presence of a time-modulated spin-orbit inter-&amp;#xD;action. Finally, we apply the approach to the case of the light driven HHG to figure out differently&amp;#xD;emerging non-linearities. Our findings initiate a new direction for harnessing HHG in both laser&amp;#xD;and precession driven ultrafast carrier dynamics.<\/jats:p>","DOI":"10.1088\/1361-648x\/adf930","type":"journal-article","created":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T22:53:01Z","timestamp":1754607181000},"source":"Crossref","is-referenced-by-count":2,"title":["Magnetic dynamics driven integer and fractional high harmonic generation arisingfrom highly nonlinear instantaneous energy levels"],"prefix":"10.1088","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7434-0540","authenticated-orcid":false,"given":"Ousmane","family":"Ly","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2025,8,7]]},"container-title":["Journal of Physics: Condensed Matter"],"original-title":[],"link":[{"URL":"https:\/\/iopscience.iop.org\/article\/10.1088\/1361-648X\/adf930","content-type":"text\/html","content-version":"am","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1088\/1361-648X\/adf930\/pdf","content-type":"application\/pdf","content-version":"am","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1088\/1361-648X\/adf930\/pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1088\/1361-648X\/adf930\/pdf","content-type":"application\/pdf","content-version":"am","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T22:53:02Z","timestamp":1754607182000},"score":1,"resource":{"primary":{"URL":"https:\/\/iopscience.iop.org\/article\/10.1088\/1361-648X\/adf930"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1088\/1361-648x\/adf930","relation":{},"ISSN":["0953-8984","1361-648X"],"issn-type":[{"value":"0953-8984","type":"print"},{"value":"1361-648X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,7]]}}}
