Unraveling the Quantum Puzzle: Comparing 'Sister' Compounds Holds the Key

Physicists have been studying the phenomenon of "Planckian" scattering in superconducting materials, which occurs when electrons scatter at high rates influenced by temperature. Researchers have now compared the compounds PdCrO2 and PdCoO2 to understand why Planckian scattering occurs in one but not the other. By examining the microscopic properties of these compounds, they have provided a quantitatively accurate description of the origin of Planckian scattering in strongly interacting metals. This research could provide insights into the puzzle of high-temperature superconductivity and lead to the development of more efficient electrical energy transfer.
