The researcher at the HZDR Institute of Radiation Physics is working on the new method alongside colleagues from the MPI-FKF, the Universities of Stuttgart and Tokyo, and other international research institutions. "Higgs spectroscopy offers us a whole new 'magnifying glass' to examine the physical processes," Dr. Higgs spectroscopy allows new insights into high-temperature superconductivity The problem is that despite many years of research efforts, their exact mode of operation remains unclear.

There is promise of progress in high temperature superconductors such as cuprates - innovative materials based on copper oxide. All known superconductors require elaborate cooling methods, which makes them impractical for everyday purposes.

Materials only 'turn on' their superconductivity below this point. Utilizing them could dramatically reduce our energy requirements - if it weren't for the fact that superconductivity requires temperatures of -140 degrees Celsius and below. Superconductors transport electric current without a loss of energy. Remarkably, the dynamics also reveal typical precursors of superconductivity even above the critical temperature at which the materials investigated attain superconductivity. An international research consortium centered around the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Max Planck Institute for Solid State Research (MPI-FKF) is now presenting the new measuring method in the journal Nature Communications.
