I am Dr. Raghavan K. Easwaran, working as an Associate Professor (Physics) & HOD at Indian Institute of Technology Patna. I work in the area of Quantum Optics (Experiment and theory), mostly focused towards Slow light using atomic mediums like alkali vapours and Ultracold atoms. Our group is working towards study of light pulse propogation in atomic media also constructing an experimental set up for Quantum memory applications under National Quantum Mission, Quantum Communication Verticals. We are currently developing an experimental facility for slow light and quantum memory applications using Electromagnetically Induced Transparency (EIT) phenomenon. Moreover this set up will be upgraded to laser cooled atoms in order to increase the efficiency of Quantum memory. This cold atoms based QM unit will be used for a multi node quantum repeater node with association with our HUB located at IIT Madras.
We also theoretically study the propagation of light pulses in a two dimensional magneto-optical trap (2DMOT) system under Electromagnetically Induced Transparency (EIT) conditions. Slow light generation in cold atomic systems are also studied. Recently we proposed novel theoretical design for the generation of slow light in 2D MOT system. TeraHertz Quantum memory, Broad band quantum memory, Multiwindow EIT using Zeeman effects etc are the other topics studied.
