Report on my stay in the SSPC Laboratory in Division of Chemistry, Graduate School of Science, Kyoto University

This report provides an overview of my scientific activities during my stay financed by the International Research Unit of Advanced Future Studies (IRUAFS) as Distinguished Visiting Professor in the Solid State Physics and Chemistry (SSPC) Laboratory in the Division of Chemistry of the Graduate School of Science at Kyoto University. I describe briefly the scientific themes that we discussed in depth, by emphasizing the prospects of future collaboration. A first part pertains naturally to our common field of expertise that includes metallic magnetism, geometric frustration in magnetic networks and topological matter. The second part describes our attempts, embryonic to this stage, to tackle transverse topics in adequacy with the transdisciplinary objectives of the IRUAFS. A first is concerned with quantum entanglement across the time that raises issues of retrocausality. The second is about the physics of the sound of the sanukite stones the magic of which appears to have been poorly investigated. I kept the same spirit, though rather multidisciplinary than transdisciplinary, in my talk at IRUAFS by describing not only my recent works on geometric frustration but also my involvement to an experimental project of search for ultra-light components of dark matter
