均匀电子气中金属相的存在性和Hartree-Fock能量的上界
Existence of a metallic phase and upper bounds of the Hartree-Fock energy in the homogeneous electron gas
摘要:
我们考虑均匀电子气的基态,我们证明了一个Hartree-Fock解决方案,由以前的模拟的动机,具有较低的能量比费米气体在大密度限制。这种溶液是金属相:密度调制对应于部分占据的晶体(位置数大于电子数)。
英文摘要:
We consider the ground state of the homogeneous electron gas and we prove that a Hartree-Fock solution, motivated by previous simulations, has lower energy than the Fermi gas in the large density limit. This solution is a metallic phase : the density modulation corresponds to a partially occupied crystal (the number of sites is larger than the number of electrons).
