How nonlinearity distorts the evidence for photoinduced superconductivity

Event Information:
Over a decade of research has suggested that some metallic compounds can be transformed into superconductors by illuminating them with intense beams of laser light. Recently, we have shown that the experimental evidence for this effect could literally be an optical illusion produced by the high-intensity laser illumination. By examining several influential results on photoinduced superconductivity in K3C60, we have identified a fundamental flaw in their analysis that exaggerates the apparent photoinduced changes to the conductivity.
