Symmetry-Driven Floquet Engineering in Multivalley SnS

These datasets contain experimental time-, polarization-, and angle-resolved photoemission spectroscopy (tr-ARPES) measurements of tin-sulfide (SnS), as well as corresponding theoretical simulations based on the time-dependent density functional theory (TDDFT). They support the findings reported in the publication: Fragkos et al., "Symmetry-Driven Floquet Engineering in Multivalley SnS" (2026). README.txt files are included, offering a detailed overview of the dataset contents. Additional metadata associated with each dataset are provided in separate metadata files.   Acknowledgments This work is supported by the Cluster of Excellence 'CUI: Advanced Imaging of Matter' of the Deutsche Forschungsgemeinschaft (DFG) - EXC 2056 - project ID 39071599 and the European Research Council (ERC-2024-SyG- 101167294 ; UnMySt), We acknowledge support from the Max Planck-New York City Center for Non-Equilibrium Quantum Phenomena.
