Collective Motions of Bose-Fermi Mixing Gases and Molecular Creative Dynamics

我们建立了描述玻色-爱因斯坦凝聚（BEC）和简并费米气体的玻色-费米混合气体（BF）随时间动力学的数值模拟方法：零温度下的TDHP+Vlasov方法和有限温度下的TDGP+VUU方法。通过这些模拟。然后，通过计算具有大变形陷阱的高炉混合气体系统的时间演化，研究了高炉混合气体中的各种集体振荡。此外，我们还研究了电偶极分子气体的集体运动与宏观图片的理论方法。

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.
