What Can Density Functional Theory Tell Us about Artificial Catalytic Water Splitting?
Density Functional Theory Artificial Catalytic Water Splitting
2014/8/21
Water splitting by artificial catalysts is a critical process in the production of hydrogen gas as an alternative fuel. In this paper, we examine the essential role of theoretical calculations, with p...
Bayesian approach to electron correlation in density functional theory
Bayesian electron correlation density functional theory Chemical Physics
2012/5/17
In the present communication the Bayesian conditional probability approach is applied to the wave function of a many-electron system that results in appearance of a quantum vector potential in the DFT...
Assessment of density functional approximations for the hemibonded structure of water dimer radical cation
Assessment of density functional approximations hemibonded structure water dimer radical cation Chemical Physics
2012/4/20
Due to the severe self-interaction errors associated with some density functional approximations, conventional density functionals often fail to dissociate the hemibonded structure of water dimer radi...

Aspects of Density Functional Resonance Theory (DFRT) [Phys. Rev. Lett. \textbf{107}, 163002 (2011)], a recently developed complex-scaled version of ground-state Density Functional Theory (DFT), are s...
Photodissociation and Density Functional Calculations of Small VmOn+ Clusters
Mass spectrometry Mass-selection Photodissociation Vanadium oxide cluster
2012/4/5
Oxygen-poor vanadium oxide clusters, V2On+ (n=1, 2), V3On+ (n=1, 2, 3), and V4O3+, were produced by laser vaporization and were mass-selected and photodissociated with 532 and 266 nm photons. The geom...
Constraining density functional approximations to yield self-interaction free potentials
Constraining density functional approximations self-interaction free potentials
2011/8/18
Abstract: Self-interactions (SIs) are a major problem in density functional approximations and the source of serious divergence from experimental results. Here, we propose to constrain the effective l...
Prediction of the derivative discontinuity in density functional theory from an electrostatic description of the exchange and correlation potential
derivative discontinuity Prediction density functional theory electrostatic description correlation potential
2011/8/5
Abstract: We propose a new approach to approximate the exchange and correlation (XC) functional in density functional theory. The XC potential is considered as an electrostatic potential, generated by...
A framework for developing new approximate electronic structure methods is presented, in which the correlation energy of a many-electron system in the ground state is computed as in the single-referen...
