Physicists split and collide ultracold atom clouds (w/ Video)

Physicists at New Zealand's University of Otago have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds of ultracold ...

Atoms and light get together to form cool, complex patterns

(Phys.org) —The physics behind some of nature's spectacular sights have been observed at very low temperatures - less than a thousandth of a degree away from absolute zero - by a collaboration of researchers from the University ...

The coldest spot in the known universe

Everyone knows that space is cold. In the vast gulf between stars and galaxies, the temperature of gaseous matter routinely drops to 3 Kelvin, or 454 degrees below zero Fahrenheit.

A single-atom light switch

With just a single atom, light can be switched between two fibre optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and communication technology.

Spinning atoms in light crystals

(Phys.org) —After more than 40 years of intense research, experimental physicists still seek to explore the rich behaviour of electrons confined to a two-dimensional crystalline structure exposed to large magnetic fields. ...
