在本文中，我们回顾了高密度和中密度下二维和三维电子气周期性基态的可能性。在 Hartree-Fock 水平上，我们在能量低于均质费米气体的所有密度下获得了显式解。在高密度区域，电子仅部分填充了接近自旋密度波的能带，正如奥弗豪泽所预测的那样。对极化二维电子气的初步变分蒙特卡罗计算证实了这些新型基态的存在。
In this paper, we review the possibility of periodic ground states of the two‐ and three‐dimensional electron gas at high and intermediate densities. At the Hartree–Fock level, we obtain explicit solutions at all densities having lower energies than the homogeneous Fermi gas. In the high‐density region, the electrons only partially fill up the band approaching spin density waves as predicted by Overhauser. Preliminary variational Monte Carlo calculations on the polarized two‐dimensional electron gas confirm the existence of these new types of ground states.
