An international team of researchers (South Korea, USA – SLAC National Accelerator Laboratory, Germany, Japan) explored a photoinduced normal state of YBCO through a charge density wave (CDW) with time-resolved resonant soft x-ray scattering, as well as a high magnetic field x-ray scattering. In the nonequilibrium state where people predict a quenched superconducting state based on the previous optical spectroscopies, they experimentally observed a similar analogy to the competition between superconductivity and CDW shown in the equilibrium state. Their results provide a critical clue that the characteristics of the photoinduced normal state show a solid resemblance to those under magnetic fields in equilibrium conditions. Their findings open opportunities, including the possibility that other materials could also be nudged into a transient superconducting state with light…read more. Open Access TECHNICAL ARTICLE
