Material Insights toward the Discovery of Quantum Phenomena

Designing materials toward exhibiting quantum phases has been a longstanding goal in condensed matter, exemplified by the noble pursuit for room temperature superconductivity, quantum spin liquids, and other exotic quantum phases of matter. I will discuss two different materials design concepts, Zintl Phase and the Kagome lattice. In the search for magnetic topological insulators, we investigated the rare earth Zintl Eu₅Sn₂As₆, a candidate magnetic topological insulator which exhibits Colossal Magnetoresistance (CMR) and hosts a rich magnetic structure intimately tied to the lattice. In the search for correlated flat band physics, we leverage the Materials Project to discover Kagome lattice materials that are likely to exhibit flat band physics. Within each example, we will discuss how our work gives us material insights into improving these materials designs toward realizing their respective quantum phenomena.
