Explore the engineering of atomic networks in crystalline materials through this 59-minute seminar from the IQUIST series. Learn how quantum applications require excitations with high fidelity and known connectivity, and discover the challenges of designing atomic networks in solid-state materials where ions exist in crystalline environments. Understand how the energy landscape determining connectivity operates at a much larger scale than modern optical and microwave applications that probe these materials. Examine the benefits of nature's tendency toward order in creating uniform bonding environments, while also addressing the significant challenge of designing atomic networks from scratch and dealing with locked-in material imperfections that cannot be corrected through post-processing. Discover how chemical rules and bonding networks are used to identify promising uninvestigated or undiscovered materials, including compounds containing rare earth ions for quantum memory applications, charge density wave materials hosting exotic excitations, and new or high-quality layered van der Waals materials. Gain insights into the complex process of crystal growth, which requires millimeter dimensions and must be grown from solutions, fluxes, or vapors - a kinetically dependent process that benefits greatly from in situ observation techniques. Learn how clearer understanding of material formation processes enables critical evaluation of computational predictions from both ab initio and machine-learned methods, while exploring novel reactions to target new phases in materials science.
