Light tsunami in a superconductor

Superconductors are materials which conduct electric currents without any resistance. At the Helmholtz-Zentrum Dresden-Rossendorf, an international research team headed by Professor Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter managed to selectively influence this resistance-free conductivity with a powerful terahertz laser. This very precise laser light turns into a vortex which moves through the superconductor like a tsunami. The results will be published in the scientific journal Nature Materials.
