Title: The use of ultracold atoms and molecules in uncovering new aspects of physics

Speaker: Dr. Rahul Sawant, M Squared Lasers Ltd., London, UK

Abstract: In this presentation, I will highlight research that utilizes ultracold atoms and molecules to delve into new realms of physics. First, I will discuss the results from one of our experiments that studied the dissipative creation of super-critical Bose-Einstein Condensate (BEC). We observe a BEC which is not in phase equilibrium with its thermal environment. The aim was to push the experiment into a region where the current theoretical predictions failed to match the experimental data. Next, I will delve into the exciting field of ultracold molecules, which offer unique opportunities to explore the intersection of physics and chemistry. Ultracold molecules hold potential for quantum simulations, but decoherence poses a significant challenge. I will discuss how the trapping laser for ultracold molecules adds decoherence to the system and report our experimental results of reducing it using electric and magnetic fields. In addition, I will also give a brief glimpse of how we plan to use ultracold atoms to build inertial sensors for navigation. In the end, I will briefly talk about my research proposal, where we will strive to study various aspects of complex quantum systems with a focus on self-organized systems. We plan to use ultracold atoms to form complex quantum systems.
