Researchers demonstrate optical backflow of light

Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. The phenomenon, theorized more than 50 years ago by quantum physicists, has never before been demonstrated ...

Using sound and light to generate ultra-fast data transfer

Researchers have made a breakthrough in the control of terahertz quantum cascade lasers, which could lead to the transmission of data at the rate of 100 gigabits per second—around one thousand times quicker than a fast ...

Vibrations on a chip feel a magnetic field

AMOLF physicists have made mechanical vibrations on a chip behave as if they were electrical currents flowing in a magnetic field. Because of their charge, electrons are influenced by magnetic fields, which curve their trajectories. ...
