弱相互作用费米气体的相关能

Correlation Energy of a Weakly Interacting Fermi Gas

Niels Benedikter, Phan Thành Nam, Marcello Porta, Benjamin Schlein, Robert Seiringer

摘要:

严格推导了高密度、弱相互作用标度区中费米气体的关联能的首阶。结果验证了随机相位近似的预测。我们的证明完善了集体玻色子化的方法在三维空间。我们近似对角化的有效哈密顿量描述近似玻色子集体激发周围的Hartree-Fock状态,而无隙和非集体激发只有一个可以忽略不计的影响的基态能量。

英文摘要:

We derive rigorously the leading order of the correlation energy of a Fermi gas in a scaling regime of high density and weak interaction. The result verifies the prediction of the random-phase approximation. Our proof refines the method of collective bosonization in three dimensions. We approximately diagonalize an effective Hamiltonian describing approximately bosonic collective excitations around the Hartree-Fock state, while showing that gapless and non-collective excitations have only a negligible effect on the ground state energy.
