(PhysOrg.com) -- When studying cold atoms, scientists often use magnetic or optical traps to keep the atoms in place. However, in some cases experimentalists want to study free atoms, avoiding the effects of a trap. "One ...
(PhysOrg.com) -- The most accurate timekeepers in the world are atomic clocks, which tell time based on the absorption of a very specific and unchanging microwave frequency, which induces electrons in an atom to “jump” ...
(PhysOrg.com) -- “People are interested in the mid-infrared,” Dan Wasserman tells PhysOrg.com. Infrared light has a wavelength longer than visible light, and many molecules have numerous very strong optical resonances ...
(PhysOrg.com) -- Since 1970, scientists have been working with “optical tweezers” - lasers that move microscopic amounts of matter using forces originating from the light matter interaction. Now, for the first time, researchers ...
Dark energy—a mysterious force pushing the universe apart at an ever-increasing rate—was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle causing the expansion.

The depths of the oceans are home to a complex ecosystem of marine organisms, but also a vast network of cables spanning the globe that aid communications. Earthquakes and tsunamis can potentially damage these important cables. ...
Despite their immense promise to solve new kinds of problems, today's quantum computers are inherently prone to error. A small perturbation in their surrounding environment— a change in temperature, pressure, or magnetic ...
