Scientists on the Raman Research Institute (RRI) have indigenously constructed an experimental facility to concurrently cool and lure a lot of sodium and potassium atoms close to absolute zero temperatures utilizing laser gentle and magnetic fields.
With this, RRI mentioned that it has joined the handful of laboratories globally to exhibit such environment friendly simultaneous manufacturing of a mix of two species of ultra-cold impartial atoms with inter-species interactions management.
Results from this experiment can deepen the knowledge required for growing quantum technologies reminiscent of quantum computing, quantum sensing and metrology, all of that are the frontier areas of analysis, RRI mentioned.
Built over a interval of 5 years, this specialised experimental facility contains 4 interconnected ultra-high vacuum chambers, the place atoms are trapped and cooled underneath a strain to the tune of 10-11 millibar (equal to 14 orders decrease than the traditional atmospheric strain).
There are a number of intricate laser techniques, optical preparations, and high-resolution detections techniques. Using methods of flashing gentle onto the atoms, the researchers mentioned that it was potential to manipulate properties of atoms and use it for taking varied measurements which are basically quantum mechanical in nature.
“Using a combination of light and magnetic field, we attempted to cool and trap a large number of sodium and potassium atoms from their mixture at near absolute zero temperature (in micro Kelvin). As the behaviour of atoms is different at such low temperatures in comparison to the atoms at room temperatures, we wanted to understand their quantum co-relations,” mentioned Saptarishi Chaudhuri from the Quantum Mixtures Laboratory (QuMix), who led the most recent experimental analysis.
