Challenge of creating accurate and effective kinetic-energy functionals
Challenge of creating accurate and effective kinetic-energy functionals is a scholarly work by Gustavo Scuseria, published in 2001 in ''Physical Review A''. The main subjects of the publication include Truncation, Kinetic theory, energy, energy, kinetic energy, thermodynamics, statistical physics, density functional theory, ice nucleus, Kinetic scheme, and physics. It is found that the gradient expansion, the Pearson-Gordon local truncation scheme, and the 4/3-Pad\'e approximant of DePristo and Kress provide reliable estimates for the total noninteracting kinetic energy.
