【摘要】 本文在“空穴”态占有几率重整化基础上,进一步引入了包括“粒子”态占有几率的重整化Hartree-Fock近似,并用LiPkin模型对此方法与Hartree-Fock近似方法进行了检验。结果表明前者比后者更接近真实解,而且占有几率图的影响与两体相互作用强度密切相关。更多还原

【Abstract】 The occupation renormalized Hartree-Fock single particle potential is extended to include the ’particle’ state occupation. The exact solution, the solution of the occupation renormalized Hartree-Fock approximation and that of the Hartree-Fock approximation are calculated in Lipkin Model. It turns out that the RHF solution is more close to the exact one than the HF solution. The effect of occupation probability depends on the strength of the interaction of the two body term.更多还原
