| 英文摘要 | applying the direct simulation monte carlo (dsmc) method developed for ultracold bose-fermi mixture gases research, we study the sympathetic cooling process of li-6 and cs-133 atoms in a crossed optical dipole trap. the obstacles to producing li-6 fermi degenerate gas via direct sympathetic cooling with cs-133 are also analyzed, by which we find that the side-effect of the gravity is one of the main obstacles. based on the dynamic nature of li-6 and cs-133 atoms, we suggest a two-stage cooling process with two pairs of crossed beams in microgravity environment. according to our simulations, the temperature of li-6 atoms can be cooled to t = 29.5 pk and t/tf = 0.59 with several thousand atoms, which propose a novel way to get ultracold fermion atoms with quantum degeneracy near pico-kelvin.
