Researchers at UChicago PME developed a computational framework that models the full optical cycle of spin defects in solids, including internal conversion, the energy-loss pathway that has resisted accurate prediction. Applied to nitrogen-vacancy centers in diamond, it matched spectroscopy data; in silicon carbide divacancies, it revealed internal conversion strongly limits triplet excited-state lifetimes, resolving a long-standing theory-experiment discrepancy.
