Periodic ground states of the electron gas in two and three dimensions
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 reg...

Summary: | 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. |
