Mostly, they result from the interaction of only pairs of particles, so called two-body interactions, even when large complex many-particle structures are formed. We show that three-particle bound states occur in a generic, experimentally accessible solid state system: antiferromagnetic spin ladders, related to high-temperature superconductors. Strikingly, this binding is induced by genuine three-particle interactions; without them there is no bound state. We compute the dynamic exchange structure factor required for the experimental detection of the predicted state by resonant inelastic x-ray scattering for realistic material parameters. Our work enables us to quantify these elusive interactions and unambiguously establishes their effect on the dynamics of the quantum many-particle state. The data provided here contains the Green function and the weights of the dynamic exchange structure factor and the corresponding Lanczos coefficients.</dc:description> <dc:identifier>https://staging-archive.materialscloud.org/record/2021.223</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:k8-v6</dc:identifier> <dc:identifier>mcid:2021.223</dc:identifier> <dc:identifier>oai:materialscloud.org:1184</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>Spin ladder</dc:subject> <dc:subject>Triplon</dc:subject> <dc:subject>Bound State</dc:subject> <dc:subject>RIXS</dc:subject> <dc:subject>CUT</dc:subject> <dc:subject>Theoretical</dc:subject> <dc:title>Bound by three-body interactions</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
