Charge-Spin Coupling as a Probe of Correlated Materials - Joao N. B. Rodrigues

The study of the quantum properties of materials is all about understanding how collective behavior arises in systems with a large number of interacting particles (electrons and nuclei). In some materials these interactions give rise to unique correlated quantum states which are behind fascinating macroscopic phenomena such as magnetism or superconductivity. We will discuss a novel efficient way of probing correlated materials which relies on quantifying how electrons in a material respond to each other. In particular, we will see how known high-temperature unconventional superconductors such as the copper oxides, iron-pnictides and iron-chalcogenides have distinctive electronic correlations that set them apart from most other materials. Such observation allows for the construction of a data-based prediction model that might help in the search for new high-temperature unconventional superconductors.
