Title: Exploring Collective Phenomena in Quantum Gases
Abstract:
Trapping and cooling atomic gases into the quantum regime is a remarkable scientific achievement in the past 20 years. The well-controlled settings of ultracold atoms are capable of realizing novel collective quantum states of matter. In this talk, I will present my research on Fermi and Bose quantum gases. In the Fermi case, we focus on recent experiments on superfluids with spin imbalance. Our model describes well the system behavior and would help identify an oscillatory pairing state that was theoretically proposed 50 years ago but not yet firmly detected in experiments. In the Bose case, we focus on optical lattices where two extremely different quantum phases, superfluid and Mott-insulator, can coexist. We discuss a new coupling in such system that induces Mott-insulators with the same occupation parity and exotic pair superfluids. Finally, by pointing out the similarity between both cases, we suggest a possibility of boson-like behaviors emerging from the Fermi system.
