Scientists create never-before-seen form of matter

Working with colleagues at the Harvard-MIT Center for Ultracold Atoms, a group led by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic have managed to coax photons into binding together to form molecules – a state of matter that, until recently, had been purely theoretical. The work is described in a September 25 paper in Nature.

Harmillisesti tuosta uudesta mteriaalista ei anneta juuri mitään tietoa. Paljonko esim toi "valo" painaa?

Eikös valo paina saman kuin on sen energia?
Lainaus:
"Most of the properties of light we know about originate from the fact that photons are massless, and that they do not interact with each other," Lukin said. "What we have done is create a special type of medium in which photons interact with each other so strongly that they begin to act as though they have mass, and they bind together to form molecules. This type of photonic bound state has been discussed theoretically for quite a while, but until now it hadn't been observed."

Harmi että tässäkin puhutaan valon "massattomuudesta" eikä fotonin energiasta mikä olisi paljon tutumpi yksikkö massalle.
