| Research Abstract |
We construct the numerical simulation method to describe the time-dependent dynamics of the bose-fermi(BF) mixing gas which includes the Bose-Einstein condensation(BEC) and the degenerate Fermi gas : the TDHP+Vlasov approach for the zero temperature and the TDGP+VUU approach for the finite temperature. By using these simulations. then, we study various kinds of collective oscillations in BF mixing gases by calculating the time evolution of these systems with largely deformed traps. Furthermore, we also investigate collective motions of electric dipolar molecular gases in a theoretical approach with the macroscopic picture.
