The physicists from German and United States on Wednesday, February 26, 2014, have claimed to have discovered a new particle called quantum droplets aka dropleton. The discovery of this particle has been published on the Nature journal, according to the scientists that the new particle has a behavior similar of water droplets or liquids in general.

The new particles including the quasiparticle, an amalgamation of the particles are smaller. This new particle is not elementary particles, but composite. The invention is useful for the development of nanotechnology, including optoelectronic devices, such as semiconductor lasers used in Blu-ray disc player.
In experiments using ultra-fast laser emission around 100 million pulses per second, the quantum droplets were observed only in the 2.5 trillion per second. Time is indeed very, very short. However, for physicists, it's stable enough to research on how light interacts with specific materials.
Examples of other quasiparticle is eksiton, pairs of electrons and "holes" or "gaps", where the energy structure of a material in which electrons missing or not found. Quantum droplet consists of five electrons and five slits. These particles have a liquid-like characteristics, such as smaller ripples or waves.
Quantum physics is a physics branch that studies the world of smallest material. This is important in describing the structure of atoms. Is the basic structure of the constituent particles of matter. Includes several entities subatomic particles, such as protons, electrons, neutrons, and quarks.
To find this new particle, the German scientists worked with a team of scientists led by Steven Cundiff of the Joint Institute for Laboratory Astrophysics (JILA) in Colorado, United States. The laser experiments performed using semiconductor of gallium and arsenic elements, in which the then newly discovered particle although a snap.
"Although it happens very quickly, it is still useful to understand that this is indeed the case," Cundiff said as quoted by Reuters, on Wednesday, February 26, 2014. Mackillo Kira, one of the researchers from the University of Marburg, Germany, said that the findings were useful in optoelectronics. Optoelectronic devices which are LED lights and lasers semiconductor used in telecommunications and Blu-ray discs. *** [EKA | FROM VARIOUS SOURCES | REUTERS | NBC NEWS]
