Scientists use laser beam to break down calcium monofloresite molecules in extremely low temperature and reduce the intermediate barrier in two-step cooling process.
Decades ago, new doors of research, which brought cooling down to individual molecules, were opened in absolute zero temperatures.
The researchers of Imperial College London's "The Center for Cold Matter" record this. To cool a moving particle means to calm it down. The technique of losing momentum by exploiting and extinguishing the atomic light is used in this method. A laser is placed in a fixed frequency to keep the atom in a restricted magnetic field.
If the particle moves away from the laser beam, then it feels like a doppler shift frequency, which is at the end of the red in the spectrum. If the particle is immune, the frequency moves towards the end of the blue.
By proper frequency the atom absorbs the photons for fixed speeds of the laser, in which an electron of the atom moves to a new power level. When the photon leaves, the electrons come back randomly. This discharge gradually calm down the ears. Doppler cooling is the name of this very cooling method. Here the losing power of the emission is found in the remaining atoms.
Atoms can be cooled by Doppler Limit. Physicists have reduced to one trillion part of one kilvin or to 0.00000000005 degrees from absolute zero temperature.
But today, physicists have only made molecules of cold atoms, such as strontium fluoride molecules. In more complex systems, all atoms do not respond to the same cooling system. To increase the range, magnetic field and laser together with magnetic fields and lasers are used to calcium monophyllaide molecules, which are enough to bring them to Doppler Limit. It is also called sisifass cooling.
In Greek myth, the royal King Sisiphas was sentenced to death as a rocks in the hills. This unlimited time-consuming task can be considered as the particle power. Instead of the mountain, physicists use a joint laser, which is polarized in such a way that the force is able to force the guard to lose momentum. Although the temperature that is available is not near at all, but it is much better than the previous records.
