摘要
计算了开边界,均匀系统和有谐振势存在的条件下,一维费米气体的态密度和密度分布,并对干净系统,在位能无序系统和跳跃能无序系统的结果进行比较。从态密度与密度分布的数值计算结果表明:无序使系统趋向于局域化。
This paper calculates the density of states and density distribution of one-dimensional fermi gas in homogeneous system or under harmonic confinement with open boundary condition,and compares the results of clean system,disorder system of on-site and hopping energy.The numerical calculation shows that disorder makes the system tend to localization.
