Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be ...

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 ...

Researchers set a record by guiding light in 45-meter-long air wave-guides. It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But ...

NASA has successfully transmitted data between Earth and two spacecraft using lasers, completing a groundbreaking experiment that could aid in future missions to other worlds. When you purchase ...

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 ...

In a discovery that could reshape how we view and understand the human brain, researchers have successfully passed a laser beam through an entire human head. While it may sound like science fiction, ...

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 ...
