Superconductivity without cooling

No resistance at room temperature: The resonant excitation of oxygen oscillations (blurred) between CuO2 double layers (light blue, Cu yellowy orange, O red) with short light pulses leads to the atoms in the crystal lattice briefly shifting away from their equilibrium positions. This shift brings about an increase in the separations of CuO2 layers within a double layer and a simultaneous decrease in the separations between double layers. It is highly probable that this enhances the superconductivity. Credit: Jörg Harms/MPI for the Structure and Dynamics of Matter

Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It is already in use in some niche areas, for example as magnets for nuclear spin tomography or particle accelerators. However, the materials must be cooled
