In a study appearing in Review of Scientific Instruments, UC Davis researchers report a refined NMR method for investigating condensed matter materials, improving the sensitivity of the method by roughly 1,000 times.
When studying complex materials, condensed matter physicists often harness the Fermi-Hubbard model to explore a material’s electric, magnetic and superconductive properties. But the model isn’t without limitations. Historically, its theoretical and experimental applications have been limited to atoms with electrons that exist in two possible states.
