Ph.D. in Physics: Tata Institute of Fundamental Research, Mumbai (2011) Thesis Title: Deep-cooled fermionic and bosonic potassium atoms in a multi-species laser-cooling and trapping set-up. Advisor: Prof. C. S. Unnikrishnan
In my thesis work, bosonic and fermionic isotopes of potassium atoms were laser-cooled in a compact 2D-3D magneto-optical trap setup. Further special sub-Doppler cooling technique, namely polarization gradient cooling was implemented to cool both the isotopes to tens of micro Kelvin. Temperatures obtained for the 39K using polarization gradient cooling were among the very first lowest temperatures reported.
