This work was supported by the National Natural Science Foundation of China (U2032213 (J. M.), 12274288 (X. W. and J. W.)), the Innovation Program for Quantum Science and Technology (2021ZD0301900 (X. W. and J. W.), 2022YFA1402702 (J. M.)), the Natural Science Foundation of Shanghai (20ZR1428400), Shanghai Pujiang Program (20PJ1408100 (X.W. and J.W.)), and Grants-in-Aid for Scientific Research (25220803 and 24244059) from MEXT. The authors would like to thank ISIS Neutron and Muon Source, the STFC Rutherford Appleton Laboratory, and the Institut Laue-Langevin facilities for the allocation of inelastic neutron scattering beam-time. The cold neutron multi-chopper spectrometer (LET, ISIS) data (https://doi.org/10.5286/ISIS.E.RB2210086) were reduced using Mantid and were analyzed using the Horace-MATLAB software package. Jianda Wu, Jie Ma, and Bella Lake conceived and coordinated the project. M. Matsuda, Akira Okutani, M. Hagiwara, Jie Ma, Konrad Puzniak, and Bella Lake synthesized the crystals. Jie Ma, Konrad Puzniak, Bella Lake, Karin Schmalzl, and C. Balz designed the experiment. Xiao Wang and Jianda Wu carried out analytical and iTEBD calculation and provided theoretical analysis. Xiao Wang, Konrad Puzniak, Jie Ma, Jianda Wu, and Bella Lake wrote the manuscript. This work was supported by the National Natural Science Foundation of China (U2032213 (J. M.), 12274288 (X.
