Introducing PROFESS 3.0: an advanced program for orbital-free density functional theory molecular dynamics simulations. (English) Zbl 1344.81010
Summary: Orbital-free density functional theory (OFDFT) is a linear-scaling first-principles quantum mechanics method used to calculate the ground-state energy of a given system. Here we present a new version of PRinceton Orbital-Free Electronic Structure Software (PROFESS) with new features. First, PROFESS 3.0 provides a set of new kinetic energy density functionals (KEDFs) which are designed to model semiconductors or transition metals. Specifically, PROFESS 3.0 includes the Huang-Carter (HC) KEDF [C. Huang and E. A. Carter, “Nonlocal orbital-free kinetic energy density functional for semiconductors”, Phys. Rev. B (3) 81, No. 4, Article ID 045206, 15 p. (2010; doi:10.1103/PhysRevB.81.045206)], a density decomposition method with fixed localized electronic density [C. Huang and E. A. Carter, “Toward an orbital-free density functional theory of transition metals based on an electron density decomposition”, Phys. Rev. B (3) 85, No. 4, Article ID 045126, 9 p. (2012; doi:10.1103/PhysRevB.85.045126)], the Wang-Govind-Carter (WGC) decomposition KEDF [J. Xia and E. A. Carter, “Density-decomposed orbital-free density functional theory for covalently bonded molecules and materials”, Phys. Rev. B (3) 86, No. 23, Article ID 235109, 15 p. (2012; doi:10.1103/PhysRevB.86.235109)], and the Enhanced von Weizsäcker (EvW)-WGC KEDF [I. Shin and E. A. Carter, “Enhanced von Weizsäcker Wang-Govind-Carter kinetic energy density functional for semiconductors”, J. Chem. Phys. 140, No. 18, 18A531 (2014; doi:10.1063/1.4869867)]. Other major new functions are included, such as molecular dynamics with different statistical mechanical ensembles and spin-polarized density optimizers.
