Tomoya Naito, Ryosuke Akashi, Gianluca Colò, Haozhao Liang, Xavier Roca-Maza

摘要:

本文将电子系统的库仑交换和关联能量密度泛函应用于核系统。结果表明,广义梯度近似下的交换泛函在几十个$ \mathrm{keV} $精度范围内与带一个可调参数的精确Fock能一致,而关联泛函由于核力的存在而不能直接应用于核系统.

英文摘要:

The Coulomb exchange and correlation energy density functionals for electron systems are applied to nuclear systems. It is found that the exchange functionals in the generalized gradient approximation provide agreements with the exact-Fock energy with one adjustable parameter within a few dozen $ \mathrm{keV} $ accuracy, whereas the correlation functionals are not directly applicable to nuclear systems due to the existence of the nuclear force.
