Abstract: Quantum materials can exhibit remarkable magnetic and electronic states because the behavior of their electrons is dominated by intense quantum effects. Quantum materials have repeatedly shifted the paradigm in condensed matter physics, proving their fundamental importance; however, these materials also hold tremendous promise for real-world applications. In this talk, I will introduce the quantum spin liquid: a strongly entangled magnetic fluid that represents the greatest departure from classical physics. While theorists have made tremendous strides in the discovery of quantum spin liquid models, experimental progress has lagged behind. A significant limitation has been the lack of real materials that can host quantum spin liquid states. In this talk, I will describe my chemical design intuition for creating a quantum spin liquid and then present the result of this design process, Er2Pt2O7, a material with the experimental hallmarks of proximity to a quantum spin liquid state.
