Effective Core Potentials ( ECP):使用单个有效势替代内核电子,内核处理中引入相对论校正。 All Electron Relativistic:处理体系中的所有电子,并在内核电子的处理中引入相对论效应。 DFT Semi-core Pseudopots (DSPP):使用单个有效势替代内核电子,内核处理中引入相对论校正。 注:ECP和DSPP 都是对21号以后的重元素进行...
semi-periodic and non-periodic boundary conditions and general geometries. DFT-FE can be run on massively parallel many-core CPU and hybrid CPU-GPU architectures (tested up to ~200,000 cores on many-core CPUs and ~24,000 GPUs on hybrid CPU-GPU architectures). DFT-FE is capable of fast ...
“Semi-local”赝势容易可视化,而“Separable”赝势更便于 数值计算目的的应用。 至此,我们已经有赝势的一般形式,但这里将不描述如何从 原子问题的解产生赝势,这个问题可以参考Bachelet的文章 prb26-4199(82) 。(6.72) 占据数 我们可以将-受价芯轨道正交化限制的价电子能量: 用不受pseudo-val与core轨道正交化限制...
As noted in the introduction, we have restricted our analysis to (semi-)local xc-functionals, since such kind of calculations are the current workhorse in computationalhigh-throughputstudies and hence constitute the uttermost majority of data stored in existing electronic-structure theory databases16. ...

The positions of the hydrogen atoms around thepseudo-octahedral Rh6core in the optimized structures of [Rh6(PH3)6H12]x(x= 0, +1, +2, +3 or +4) varied depending on the overall charge on the cluster. The number of semi-bridging hydrides increased (semi-bridging hydrides have two ...
While the atom-centered basis sets are superior regarding these aspects, they, however, suffer from a number of different problems, most importantly, from the BSSE issues due to an incompleteness of the basis set as well as from the so-called pseudo linear-dependence problem. In contrast to ...
