d维费米气体的Lindhard函数

Lindhard function of a d-dimensional Fermi gas

Bogdan Mihaila

摘要:

本文详细讨论了自旋为1/2的费米子系统在无规相位近似下的介电响应函数的推导。结果的响应函数的费米气体在一个,两个和三个维度,可以得到封闭的形式,并表示基线发展的教学理解的影响的相关性的响应函数在相互作用系统的费米子。

英文摘要:

We review in detail the derivation of the dielectric response function of a noninteracting system of spin-1/2 fermions in the random-phase approximation. Results for the response function of a Fermi gas in one, two and three dimensions can be obtained in closed form, and represent the baseline for developing a pedagogical understanding of the effect of correlations on the response functions in interacting systems of fermions.
