Many-body quantum systems have come under intense focus in recent years to enable a number of quantum simulation and sensing tasks. Neutral atoms, ions and solid state qubits have all emerged as key platforms for inquiry. One key set of questions concerns the ability of these delicately tailored quantum systems to relax to equilibrium when they are isolated from the environment, and whether such dynamics might have universal features. Research in our laboratory on magnetic quantum fluids comprised of spin-1 Bose-Einstein condensed atoms (BECs) has a remarkable potential to address this problem. In this talk I will show data from our lab demonstrating the rich interplay between many actors--magnetic interactions between spins, the influence of external magnetic fields, and the spatial quantum dynamics of many interacting modes that all compete to determine the non-equilibrium behavior.
Dr. Raman Biosketch: Dr Chandra Raman is Associate Professor in the School of Physics at Georgia Tech where he performs experimental research on ultracold atomic gases and builds miniature atomic systems for quantum sensing applications. His work aims to understand the basic physics of complex quantum systems to harness them for applications. His group at Georgia Tech has uncovered new properties of quantized vortices, spin textures and quantum phase transitions in ultracold Bose gases, work for which he was awarded Fellowship in the American Physical Society in 2013. From 2013-15 he took a leave of absence to work in industry to better understand real world atomic sensors, work which he has translated into his laboratory today.
