The light that surrounds us is composed of two main components. Scientists call it as a wave particle duality. This means that the light has the nature of the waves, but also moves like photons or particles. Physicists at the University of Bonn managed to create a new source of light, i.e. What is called Bose-Einstein condensate. This light source consisting of photons.
In order for this experiment is successful, it takes the condition where there is no light at all, says Julian Schmitt, one of physicists at the University of Bonn. "For this experiment we work at low intensity, so conditions should be dark total, in order for photons, which do not originate from the resonator, don't mess up our data."
Over the years, the photon is said to be unable to form a Bose-Einstein condensate, because the photon can not be cooled as atom. "The problem is, if the light drop in temperature, then light source also turns off," said Martin Weitz, Professor of physics at the University of Bonn. Weitz is one of the scientists who publish study photon super.
Weitz provide examples, if the light was extinguished filament tungsten bulb, which cools changed colour from yellow to red, along with the absorption of a photon by Atomic which surrounds it. This process lasts until all the photons vanished.
To create conditions of Bose-Einstein in atom, atom is cooled to zero degrees Kelvin or minus 273 degrees Celsius. But, this could not be done on the photon, because the photons will be absorbed into the atom before reaching the temperature.
The Weitz and his team is a wide gap in the photon traps one micron between two highly reflective mirror. After the photons are caught, scientists add pigment molecules. "We cool the photons with spread light molecule pigment and therefore, light it cools to the same with pigment at room temperature. We then analyze and found that if the number of photons that put quite a lot, then we can observe the existence of a Bose-Einstein condensate, "explains Weitz.
Photon super, so as the physicist at the University of Bonn to eksperimennya results. The reason, this resembles the condition condition photon Super atom. But according to some scientists, the term is actually less appropriate because particles photons not forming new molecules. Only nature just changed. Physicists from the University of Toronto Aephraim Steinberg, an allusion to the armed forces are made up of thousands of soldiers, not super, but others say is a combination of a number of soldiers.
In spite of differences of opinion as to the results of experiments related do physicists Weitz and his team, Steinberg acknowledges that this is a sensation of findings in the field of quantum physics.
The question now is, what can be done with this super photon? Martin Weitz mentions a number of future applications can take advantage of the photon super, although he thinks that, at the moment everything is still in the stages of the theory.
One idea is to develop the short wave laser operating in the spectrum of x-rays or ultra violet. Until recently, this laser can not be realized because of her high amounts of energy required. According to Weitz, this problem can be overcome because the experiments conducted at the University of Bonn was not takes a lot of energy.
Laser operating in the ultra violet rays of the spectrum and x-rays can be used to make the chip designer-chip computers that are more complex. But until the moment arrives, Weitz and his team at the University of Bonn continue research Photonic Bose-Einstein condensate. They plan to replace liquid pigment molecules with solid pigment. It is expected to make the system the more slender and photonic easily exploited.
