Dipole Moment Calculations Using Multiconfiguration Pair-Density Functional Theory and Hybrid Multiconfiguration Pair-Density Functional Theory [PDF]

open access: yes, 2021
The dipole moment is the molecular property that most directly indicates molecular polarity. The accuracy of computed dipole moments depends strongly on the quality of the calculated electron density, and the breakdown of single-reference methods for ...

Current-density functional theory for bosonic superfluids

open access: yesJournal of Physics Communications, 2023
A finite-temperature current-density functional theory for bosonic superfluids (sf-CDFT) in the thermal equilibrium state is proposed herein. In the sf-CDFT, hydrodynamic physical quantities, such as particle number density, current density, and the ...

Density functional theory of electrowetting [PDF]

open access: yesPhysical Review E, 2014
The phenomenon of electrowetting, i.e., the dependence of the macroscopic contact angle of a fluid on the electrostatic potential of the substrate, is analyzed in terms of the density functional theory of wetting. It is shown that electrowetting is not an electrocapillarity effect, i.e., it cannot be consistently understood in terms of the variation of

Density-functional fluctuation theory of crowds

open access: yesNature Communications, 2018
Tools from statistical physics can be used to investigate a large variety of fields ranging from economics to biology. Here the authors first adapt density-functional theory to predict the distributions of crowds in new environments and then validate ...

Repulsively diverging gradient of the density functional in the reduced density matrix functional theory

open access: yesNew Journal of Physics, 2021
The reduced density matrix functional theory (RDMFT) is a remarkable tool for studying properties of ground states of strongly interacting quantum many body systems.

Existence and convergence results for the Galerkin approximation of an electronic density functional [PDF]

open access: yes, 2010
We formulate and analyze a model for the study of finite clusters of atoms or localized defects in infinite crystals based on orbital-free density functional theory.

Consistent Improvement on Both Exchange and Correlation within Hybrid Multiconfiguration Pair-density Functional Theory: tB4LYP [PDF]

open access: yes, 2023
The great success of hybrid density functional approximations, e.g.~B3LYP and PBE0, is demonstrated by their substantial improvements over their parent methods, i.e.~the Hartree-Fock approximation and the generalized gradient approximation.

Investigation of structure and vibrational properties of cyclobutane pirimidine dimer [PDF]

open access: yesHemijska Industrija, 2013
We performed a theoretical analysis of the structure and vibrational properties of cyclobutane pyrimidine dimer, which is the main product in a photochemical reaction involving two molecules of 1-methylthymine.
