    实验上超冷简并费米气体的获得及分子BEC(玻色-爱因斯坦凝聚)的成功观测,使得对低温费米气体性质的理论研究成为一个热门话题。本论文对超冷费米气体的热力学性质做了若干理论研究,研究内容包括:球对称外势约束下弱相互作用费米气体的坐标和动量分布,考虑正-反粒子对产生的相对论性理想费米气体的热力学性质以及满足q-形变统计的理想费米气体的性质特征。本论文得到的结论将有利于进一步深入理解低温下费米气体的简并特性,为揭示各种宏观量子效应的实质提供理论参考。本论文的主要内容安排如下: 第二章基于平均场近似,研究了球对称外势约束下弱相互作用费米气体的坐标和动量分布,探讨了外势、粒子间相互作用和系统温度对粒子在...The achievements of degenerate Fermi gases and the successful observations of molecular BEC (Bose-Einstein condensation) in experimental researches have created a wave of renewed interest in the theoretical study of the low temperature properties of Fermi gases. The dissertation is contributed to the investigations on the thermodynamic characteristics of ultracold Fermi gases, which include the sp...学位:理学硕士院系专业:物理与机电工程学院物理学系_凝聚态物理学号:2005130165
