Quantum many-body theories have been extensively used in our research work applied in atomic, molecular, and ultra-cold microscopic particles. Precision estimations of fundamental constants of nature, like, different electromagnetic and weak nuclear moments, weak charge using electronic transitions in atoms and molecules, are one of the thrust areas of modern research in science to probe the standard model of particle physics as well as precision improvement of atomic/molecular clocks. Estimating the astrophysical abundances of atomic and molecular species in both neutral or ionic forms using the precise electronic transitions are the other avenue of our research.
Over the last couple of years, our research is focused on the interaction of ultra-cold atoms and molecules with light, especially optical vortex. Our work shows the transfer mechanism of orbital angular momentum from light to matter, which is only consistent formalism with present-day experiments. Our proposed experimental technique to estimate the value and orientation of matter vortex without collapsing the quantum state is taken up by an eminent experimental laboratory around the world. Further, we study the non-linear dynamics in the ultra-cold systems and propose to estimate some physical parameters by observing instability patterns in Bose-Einstein condensation.
