The magnetic moment of the muon—a tiny property of a tiny particle—has long puzzled physicists. Experiments and theory haven’t quite matched up, leaving open the thrilling possibility of discovering ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'. When you shine light through almost any transparent material, the gridlock of ...

When it comes to electromagnetic waves, humans can really only directly perceive a very small part of the overall spectrum, ...

New ultrafast method for controlling magnetic materials might enable next-generation information processing technologies. This illustration shows that a pair of intense THz laser pulses drives spin ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

In a breakthrough for next-generation technologies, scientists have learned how to precisely control the behavior of tiny waves of light and electrons, paving the way for faster communications and ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...

Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...

Ordinarily, light waves pass through each other without any trouble. But when quantum mechanics is involved, something strange happens: photons can interact through the creation of virtual particles ...
