A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

Scientists have demonstrated that light alone can reversibly control magnetism in a topological material. Researchers at the University of Basel and ETH Zurich have found a way to flip the magnetic ...

For the first time, physicists have generated and observed stable bright matter-wave solitons with attractive interactions ...

Scientists enable excitons to surpass light to transform materials and open new advanced paths to quantum devices.

Physicists are no longer content to let atoms blur into invisibility. By squeezing light into pulses that last just billionths of a billionth of a second and pairing them with cameras that tick at ...

By shining a focused laser beam onto a sample of material, a team at the Paul Scherrer Institute (PSI) and ETH Zürich showed ...

However, the PowerLight system is a step toward real-world deployment in mobile platforms. Recent testing has proved the viability of the transmitter and receiver, but PowerLight has yet to conduct ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...
