My research area can be broadly classified as Quantum Optics. Through quantum optical phenomena, we are interested in understanding the nature of quantum correlation transfer between matter and light variables. In our experiments, we study quantum interactions between room temperature and/or laser cooled Alkali atoms with photons.
In these studies, our emphasis is on understanding the generation and quantification of non-linear quantum correlations at very low light intensities.
We map our results to analogous phenomena in varied architectures such as cavity opto-mechanical and circuit QED systems. We do both experimental and theoretical investigations though most of our time is spent on building good experiments.
