{"doi":"10.33425/2690-8077.1077","title":"Application of Floquet-Magnus Expansion During the Phase Modulated Lee-Goldburg Radiation in Solid State NMR","abstract":"This work uses the Floquet-Magnus expansion approach to investigate the spin system evolution during the phase modulate Lee-Goldburg radiation experiment. Until now, the Frequency switched LeeGoldburg and its variant called the Phase module Lee-Goldburg have been treated by only the average Hamiltonian theory and the bimodal Floquet approach. In this article, we use the expansion schemes of the Floquet-Magnus expansion to calculate the effective Hamiltonian and propagator during the spin dynamics. We present a remarkable iterative approach for the Floquet-Magnus expansion. Our work unifies and generalizes existing results of the Floquet-Magnus expansion and delivers illustrations of novel springs that boost previous applications that are based on the classical information. The method presented could plays a major role in the interpretation of a number of fine NMR experiments in solids, which provide significant new insight in spin physics. The generality of the work points to potential applications in problems related in solid-state NMR and theoretical developments of spectroscopy as well as interdisciplinary research areas whenever they include spin dynamics concepts. The considered method of Floquet-Magnus expansion has recently found new major areas of applications such as in topological materials..","journal":"Japan Journal of Research","year":2023,"id":411573,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9583,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1092022,"name":"Aissata Diop","orcid":null,"position":1,"is_corresponding":false},{"id":1192272,"name":"Paulin J.
