Semilocal and hybrid meta-generalized gradient approximations based on the understanding of the kinetic-energy-density dependence.

چکیده
We present a global hybrid meta-generalized gradient approximation (meta-GGA) with three empirical parameters, as well as its underlying semilocal meta-GGA and a meta-GGA with only one empirical parameter. All of them are based on the new meta-GGA resulting from the understanding of kinetic-energy-density dependence [J. Sun, B. Xiao, and A. Ruzsinszky, J. Chem. Phys. 137, 051101 (2012)]. The obtained functionals show robust performances on the considered molecular systems for the properties of heats of formation, barrier heights, and noncovalent interactions. The pair-wise additive dispersion corrections to the functionals are also presented.

Semilocal density functional obeying a strongly tightened bound for exchange.
Because of its useful accuracy and efficiency, density functional theory (DFT) is one of the most widely used electronic structure theories in physics, materials science, and chemistry. Only the exchange-correlation energy is unknown, and needs to be approximated in practice. Exact constraints provide useful information about this functional. The local spin-density approximation (LSDA) was the ...
متن کاملDouble-hybrid density-functional theory with meta-generalized-gradient approximations.
We extend the previously proposed one-parameter double-hybrid density-functional theory [K. Sharkas, J. Toulouse, and A. Savin, J. Chem. Phys. 134, 064113 (2011)] to meta-generalized-gradient-approximation (meta-GGA) exchange-correlation density functionals. We construct several variants of one-parameter double-hybrid approximations using the Tao-Perdew-Staroverov-Scuseria (TPSS) meta-GGA funct...

متن کاملMolecular and Solid-State Tests of Density Functional Approximations: LSD, GGAs, and Meta-GGAs
Results from numerical tests of nine approximate exchange]correlation energy functionals are reported for various systems—atoms, molecules, surfaces, and Ž . bulk solids. The functional forms can be divided into three categories: 1 the local spin Ž . Ž . Ž . Ž . density LSD approximation, 2 generalized gradient approximations GGAs , and 3 meta-GGAs. In addition to the spin densities and their f...
متن کاملWorkhorse semilocal density functional for condensed matter physics and quantum chemistry.
Semilocal density functionals for the exchange-correlation energy are needed for large electronic systems. The Tao-Perdew-Staroverov-Scuseria (TPSS) meta-generalized gradient approximation (meta-GGA) is semilocal and usefully accurate, but predicts too-long lattice constants. Recent "GGA's for solids" yield good lattice constants but poor atomization energies of molecules. We show that the cons...
