Mott insulators are archetypal examples of quantum materials. Strong interest in these systems has arisen due in part to the insulator-to-metal transition that some exhibit when the balance between on-site Coulomb repulsion and hopping is overturned via temperature, doping, pressure or, as more recently demonstrated, photoexcitation or the application of short electric field pulses. I will...

Application of external pressure acts as clean tuning parameter of inter-atomic distances and bond angles and therefor allows for precise control of magnetic interactions in condensed matter. Extreme conditions can thus be used to stabilize novel quantum phases and drive systems close to quantum criticality where new and exciting phenomena are expected. I will show how recent advances in...

Y-kapellasite (Y3Cu9(OH)19Cl8) materializes an anisotropic kagome model with 3 different nearest neighbor interactions, yielding a rich phase diagram [1]. Besides two long range ordered phases, this phase diagram features a large spin liquid area, which encompasses the isotropic kagome model. Noticeably the large difference in the Y and Cu radii prevents inter-site mixing and the anisotropic...

Hydrostatic pressure provides a clean and continuous route to tune competing electronic phases in quantum materials, offering unique insights into the relationship between multiple emergent quantum phenomena. This approach is particularly powerful in layered systems, where pressure directly modifies interlayer coupling and electronic structure without introducing disorder. In this context, the...
