Manipulation of orbital angular momentum (OAM) states in ultracold Bose gase
We produce a rubidium Bose-Einsten-condesate (BEC) in a spherical optical dipole trap with a temperature of about 50 nK. We transfer the orbital-angular momentum (OAM) of optical field to ultracold atoms using the Raman coupling technique. On this special system, we will explore exotic OAM states in quantum gases and their potential applications in quantum processing and precision measurment. Some research directions are summarized as follows.

Non-equillibrium behaviors with many-body interactions in denerate Fermi gases
We produce 6Li degenerate Fermi gases using the evaporative cooling in an optical dipole trap. We tune the inter-atomic interactions usiing the magnetic Feshbach resonance or modulate the trapping potential by adjusting the optical trap. We mainly want to explore non-equillibium behaviors with many-body interactions in Fermi gases. Some research directions are summarized as follows.
