A team of physicists has discovered that virtual charges, which exist only during brief interactions with light, play a critical role in ultrafast material responses. Using attosecond pulses on diamonds, they showed these hidden carriers significantly influence optical behavior. The findings could accelerate the development of petahertz-speed devices, unlocking a new era of ultrafast electronics.
