Light-Induced Superconductivity (image) DOE/Brookhaven National Laboratory Share Print E-Mail Caption In equilibrium (top), the charge stripe "ripples" run perpendicular to each other between the copper-oxide layers of the material. When a mid-infrared laser pulse strikes the material (middle), it "melts" these conflicting ripples and induces superconductivity (bottom). The experimenters used a carefully synchronized X-ray laser to take this femtosecond-fast "movie" to reveal how quickly the charge stripes melt.
