Physicists have made an unexpected discovery known as Pines' Demon in a metal called strontium ruthenate. Pines' Demon is a type of plasmon, which is an energy disturbance in a material, but what sets it apart is that it operates without any electrical charge. Plasmons are typically observed in 2D metals and are difficult to detect, but strontium ruthenate behaves predictably at cooler temperatures, making it easier to study. The presence of Pines' Demon in strontium ruthenate could have implications for understanding superconductivity, which is the ability of certain materials to conduct electricity without resistance. Researchers are now interested in studying other metals with multiple electron bands to learn more about these phenomena and uncover secrets about superconductivity.
