Superconductors carry an electric current without resistance only at low temperatures. Now, for the first time, scientists have turned a ceramic crystal into a superconductor even at room temperature, using an ultrashort mid-infrared flash of light. The superconducting state survived only for a couple of picoseconds (millionth of a microsecond), and the researchers found that this light-induced state is based on certain distortions of the material’s crystal lattice. These findings may aid the quest for higher temperature superconductors and pave the way for novel applications.
