The standard Kohn-Sham formulation of density functional theory (DFT) is limited, for practical reasons, to systems of less than about 50-100 atoms. The computational effort scales as N, where Nat is the number of atoms and 2 3. (By comparison, conventional configuration interaction methods ...
Density functional theory (DFT) calculations were performed on a model of a ferrihydrite nanoparticle interacting with chromate ( $$ {\text{CrO}}_{4}^{2 - } $$ ) in water. Two configurations each of monodentate and bidentate adsorbed chromate as well as
was included in the analysis58,59,60.The potential energy surfaces of the reaction between the selected lignans and the HOO• radical were investigated based on the calculation of the transition states, intermediates, products and the intrinsic reaction coordinate at the same level of theory. The...
The marriage of density functional theory (DFT) and deep-learning methods has the potential to revolutionize modern computational materials science. Here we develop a deep neural network approach to represent the DFT Hamiltonian (DeepH) of crystalline ma
In a previous paper [9] we analyzed the process of the thermal reaction SP⇆ME by performing quantum mechanical calculations at the Density Functional Theory (DFT) level on the ground state of the well-known nitro-substituted spirobenzopyran 1',3'-dihydro-6-nitro-1',3',3'-trimethylspiro[...

Introduction: Conceptual vs Fundamental and Computational Aspects of DFT It is an understatement to say that the density functional theory (DFT) has strongly influenced the evolution of quantum chemistry during the past 15 years; the term "revolutionalized" is perhaps more appropriate. Based on the...
