介观超导体中配对的密度矩阵泛函
Density-matrix functionals for pairing in mesoscopic superconductors
摘要：
基于单粒子占有数的泛函理论发展成对。这个功能，概括了BCS的方法，直接纳入由于粒子数守恒的校正。的功能是基准与配对的哈密顿量，并完美地再现任何粒子数和耦合的能量。
英文摘要：
A functional theory based on single-particle occupation numbers is developed for pairing. This functional, that generalizes the BCS approach, directly incorporates corrections due to particle number conservation. The functional is benchmarked with the pairing Hamiltonian and reproduces perfectly the energy for any particle number and coupling.
