Caption
When nickel oxide (NiO) is excited with ultrashort UV light pulses, electron repulsions briefly become weaker, making the insulator behave more like a metal. To capture this effect, the researchers probed the material with multicolored UV pulses and measured their absorption and reflectivity. The results reveal unprecedented control over electron repulsions using light.
