Scientists on the Raman Analysis 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 mild 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.

Outcomes from this experiment can deepen the data required for creating quantum applied sciences corresponding to quantum computing, quantum sensing and metrology, all of that are the frontier areas of analysis, RRI mentioned.

Constructed over a interval of 5 years, this specialised experimental facility contains 4 interconnected ultra-high vacuum chambers, the place atoms are trapped and cooled beneath a strain to the tune of 10-11 millibar (equal to 14 orders decrease than the conventional atmospheric strain).

There are a number of intricate laser techniques, optical preparations, and high-resolution detections techniques. Utilizing strategies of flashing mild onto the atoms, the researchers mentioned that it was doable to control properties of atoms and use it for taking varied measurements which might be 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 newest experimental analysis.
