Researchers get trapped photons to act like massive particles

http://arstechnica.com/science/news/2010/1...e-particles.ars


A Bose-Einstein Condensate is a strange substance. When a set of appropriate particles are cooled so that they all occupy a ground state, they begin to exhibit wave-like properties that enable them to behave as a superfluid, moving without any turbulence or resistance. But getting enough particles, such as atoms, to occupy a single low-energy state requires that they be chilled down to a fraction of a Kelvin above absolute zero, which meant that the first observation of a BEC didn't occur until 1995. Now, researchers have found a way to create a room-temperature BEC, but it required the use of unexpected material: light
"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."

Leuk artikel:


...They're not entirely sure what to do with it at the moment, but suggest it has enough properties that are distinct from a standard laser that some use might be figured out. ...


Gelukkig zijn er dus nog labs waar onderzoekers hun gang kunnen gaan zonder te zorgen om of het morgen wel geld kan opleveren.
