Tractor beams come to life

Tractor beams, energy rays that can move objects, are a science fiction mainstay. But now they are becoming a reality -- at least for moving very tiny objects.

Scientists isolate, hold, photograph individual Rubidium 85 atom

(PhysOrg.com) -- In a major physics breakthrough, University of Otago scientists have developed a technique to consistently isolate and capture a fast-moving neutral atom - and have also seen and photographed this atom for ...

Levitating objects with light

Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects' surfaces.

The Power of Light: Moving Macroscopic Amounts of Matter

(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 ...

Quantum optical cooling of nanoparticles

When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, ...
