Experiment takes 'snapshots' of light, stops light, uses light to change properties of matter

Researchers performed an ultrafast microscopy experiment, where they trapped green light pulses of 20 fs duration as composite light-electron density fluctuation waves and imaged their propagation on a silver surface at the speed of light.

Quantum nanodevice can be both a heat engine and a fridge at the same time

The device is one of the first to test how quantum effects, which govern the behavior of particles on the smallest scale, might one day be exploited to enhance the performance of nanotechnologies.
