三维电子气的Hartree-Fock解的性质
Properties of Hartree-Fock solutions of the three-dimensional electron gas
摘要:
在前一封信中,L。Baguet等人,(Phys. Rev. Lett. { \bf 111},166402(2013))中,我们在Hartree-Fock近似下给出了三维均匀电子气的基态相图,从而在高密度下产生无公度晶体态。在这里,我们分析这些解决方案的属性。特别是,在高密度下,我们发现了无公度晶体的普遍行为,强烈支持自旋密度波基态的存在。
英文摘要:
In a previous letter, L. Baguet et al., (Phys. Rev. Lett. {\bf 111}, 166402 (2013)), we presented the ground state phase diagram of the homogeneous electron gas in three dimensions within the Hartree-Fock approximation yielding incommensurate crystal states at high density. Here, we analyze the properties of these solutions. In particular, at high density we find universal behavior of the incommensurate crystal strongly supporting the existence of a spin density wave ground state.
