A CSFG-based neural network basis-selection method for large-scale RCI calculations within GRASPG

Chaofan Shi, Shaowei Tian, Ran Si +3

We present a neural network (NN) basis-selection method for large-scale relativistic configuration interaction (RCI) calculations in GRASPG. The method employs configuration state…

Non-orthogonal extension of Graspg - dynamic electron correlation for large and compact active spaces

Sijie Wu, Ran Si, Chongyang Chen +3

Accurate relativistic multiconfiguration calculations of correlation-sensitive atomic properties are often limited by the rapid growth of configuration state function expansions wh…

Atomic data benchmarked by Large-scale Multiconfiguration Dirac-Hartree-Fock Calculations for Beryllium

Sijie Wu, Shaowei Tian, Ran Si +6

The multiconfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction (RCI) methods are used to provide excitation energies, radiative transition data, lifet…
