Temperature-Dependent Behavior of Confined Many-electron Systems in the Hartree-Fock Approximation
Travis Sjostrom, Frank E. Harris, S. B. Trickey
Many-electron systems at substantial finite temperatures and densities present a major challenge to density functional theory. Very little is known about the free-energy behavior o…
An accurate few-parameter ground state wave function for the Lithium atom
Nicolais L. Guevara, Frank E Harris, Alexander V Turbiner
A simple, seven-parameter trial function is proposed for a description of the ground state of the Lithium atom. It includes both spin functions. Inter-electronic distances appear i…
Recurrence Formulas for Fully Exponentially Correlated Four-Body Wavefunctions
Frank E. Harris
Formulas are presented for the recursive generation of four-body integrals in which the integrand consists of arbitrary integer powers (>= -1) of all the interparticle distances r_…
Constraint-based, Single-point Approximate Kinetic Energy Functionals
V. V. Karasiev, R. S. Jones, S. B. Trickey +1
We present a substantial extension of our constraint-based approach for development of orbital-free (OF) kinetic-energy (KE) density functionals intended for the calculation of qua…
