In 1956, David Pines predicted that a distinct type of plasmon, dubbed a \"demon,\" could exist in three-dimensional metals containing more than one species of charge carrier. Consisting of out-of-phase movement of electrons in different bands, demons are acoustic, electrically neutral, and do not couple to light, so have never been detected in an equilibrium, three-dimensional metal. Nevertheless, demons are believed to be critical for diverse phenomena including phase t","authors_text":"A. A. Husain, B. Uchoa, C. Sow, E. W. Huang, H. Yang, M. Mitrano, M. S. Rak, P. Abbamonte, P.
