From sustainable energy to quantum computers: high-temperature superconductors have the potential to revolutionize today's technologies. Despite intensive research, however, we still lack the necessary understanding to develop these complex materials for widespread application. "Higgs spectroscopy" could bring about a watershed: It reveals the dynamics of paired electrons in superconductors. A team centered around Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Max Planck Institute for Solid State Research (MPI-FKF) presents the new measuring method in Nature Communications (DOI: 10.1038/s41467-020-15613-1).
