Silver(II) fluoride is a strongly correlated charge transfer insulator, with characteristics remarkably similar to those of parent high-temperature superconducting cuprates. AgF2 has the potential to be the basic building block to a new class of strongly correlated materials with fascinating properties. The purpose of SILVERPATH is to develop appropriate models to characterize and predict magnetic, metallic and superconducting properties by combining analytical and computational methods. In collaboration with leading chemistry and experimental groups silver fluorine based materials and heterostructures will be designed, possible routes to metallization explored, and their properties studied.

The project will ensure large progress in understanding low-dimensional quantum magnetism and has great potential to contribute to the discovery of a new class of high-temperature superconductors. The project will give the ER the opportunity to follow all the processes in the construction of a theory for a quantum material, from the model building and parameter determination to the prediction of physical properties, putting her in a position of leadership in this class of correlated materials and ready to attack any new material in the field. Moreover, SILVERPATH will contribute to strengthen the transfer of knowledge between condensed matter physics and chemistry communities.
