HOMO-LUMO Intervals from Modern Density Functionals as Fundamental Gap Estimators

H. Francisco, Javier Carmona-Espíndola, A. C. Cancio +2

Use of the Kohn-Sham eigenvalue gap (highest occupied molecular orbital to lowest unoccupied, HOMO-LUMO) as a fundamental gap (I-A, I= ionization potential, A= electron affinity) e…

How Accurately Can We Describe Spin Crossover?

Angel Albavera-Mata, Daniel Mej{í}a-Rodr{í}guez, Niranjan Govind +3

The complicated physicochemical properties of metal complexes that exhibit thermal spin crossover make it difficult for routine electronic structure calculations to yield an accura…

Performance Improvement of Deorbitalized Exchange-Correlation Functionals

H. Francisco, B. Thapa, S. B. Trickey +1

Deorbitalization of a conventional meta-generalized-gradient exchange-correlation approximation replaces its dependence upon the Kohn-Sham kinetic energy density with a dependence…

Trivial Constraints on Orbital-free Kinetic Energy Density Functionals

Kai Luo, S. B. Trickey

Kinetic energy density functionals (KEDFs) are central to orbital-free density functional theory. Limitations on the spatial derivative dependencies of KEDFs have been claimed from…

On the Kubo-Greenwood Model for Electron Conductivity

James Dufty, Jeffrey Wrighton, Kai Luo +1

Currently, the most common method to calculate transport properties for materials under extreme conditions is based on the phenomenological Kubo-Greenwood method. The results of an…

Nonempirical Semi-local Free-Energy Density Functional for Matter Under Extreme Conditions

Valentin V. Karasiev, James W. Dufty, S. B. Trickey

Realizing the potential for predictive density functional calculations of matter under extreme conditions depends crucially upon having an exchange-correlation (XC) free energy fun…

Revised Thomas-Fermi Approximation for Singular Potentials

James W. Dufty, S. B. Trickey

Approximations to the many-fermion free energy density functional that include the Thomas-Fermi (TF) form for the non-interacting part lead to singular densities for singular exter…

Issues and Challenges in Orbital-free Density Functional Calculations

V. V. Karasiev, S. B. Trickey

Solving the Euler equation which corresponds to the energy minimum of a density functional expressed in orbital-free form involves related but distinct computational challenges. On…
